/**
 * EventDispatcher provides methods for managing queues of event listeners and dispatching events.
 *
 * You can either extend EventDispatcher or mix its methods into an existing prototype or instance by using the
 * EventDispatcher {{#crossLink "EventDispatcher/initialize"}}{{/crossLink}} method.
 * 
 * Together with the CreateJS Event class, EventDispatcher provides an extended event model that is based on the
 * DOM Level 2 event model, including addEventListener, removeEventListener, and dispatchEvent. It supports
 * bubbling / capture, preventDefault, stopPropagation, stopImmediatePropagation, and handleEvent.
 * 
 * EventDispatcher also exposes a {{#crossLink "EventDispatcher/on"}}{{/crossLink}} method, which makes it easier
 * to create scoped listeners, listeners that only run once, and listeners with associated arbitrary data. The 
 * {{#crossLink "EventDispatcher/off"}}{{/crossLink}} method is merely an alias to
 * {{#crossLink "EventDispatcher/removeEventListener"}}{{/crossLink}}.
 * 
 * Another addition to the DOM Level 2 model is the {{#crossLink "EventDispatcher/removeAllEventListeners"}}{{/crossLink}}
 * method, which can be used to listeners for all events, or listeners for a specific event. The Event object also 
 * includes a {{#crossLink "Event/remove"}}{{/crossLink}} method which removes the active listener.
 *
 * <h4>Example</h4>
 * Add EventDispatcher capabilities to the "MyClass" class.
 *
 *      EventDispatcher.initialize(MyClass.prototype);
 *
 * Add an event (see {{#crossLink "EventDispatcher/addEventListener"}}{{/crossLink}}).
 *
 *      instance.addEventListener("eventName", handlerMethod);
 *      function handlerMethod(event) {
 *          console.log(event.target + " Was Clicked");
 *      }
 *
 * <b>Maintaining proper scope</b><br />
 * Scope (ie. "this") can be be a challenge with events. Using the {{#crossLink "EventDispatcher/on"}}{{/crossLink}}
 * method to subscribe to events simplifies this.
 *
 *      instance.addEventListener("click", function(event) {
 *          console.log(instance == this); // false, scope is ambiguous.
 *      });
 *      
 *      instance.on("click", function(event) {
 *          console.log(instance == this); // true, "on" uses dispatcher scope by default.
 *      });
 * 
 * If you want to use addEventListener instead, you may want to use function.bind() or a similar proxy to manage scope.
 *

/**
 * PreloadJS provides a consistent way to preload content for use in HTML applications. Preloading can be done using
 * HTML tags, as well as XHR.
 *
 * By default, PreloadJS will try and load content using XHR, since it provides better support for progress and
 * completion events, <b>however due to cross-domain issues, it may still be preferable to use tag-based loading
 * instead</b>. Note that some content requires XHR to work (plain text, web audio), and some requires tags (HTML audio).
 * Note this is handled automatically where possible.
 *
 * PreloadJS currently supports all modern browsers, and we have done our best to include support for most older
 * browsers. If you find an issue with any specific OS/browser combination, please visit http://community.createjs.com/
 * and report it.
 *
 * <h4>Getting Started</h4>
 * To get started, check out the {{#crossLink "LoadQueue"}}{{/crossLink}} class, which includes a quick overview of how
 * to load files and process results.
 *
 * <h4>Example</h4>
 *      var queue = new createjs.LoadQueue();
 *      queue.installPlugin(createjs.Sound);
 *      queue.on("complete", handleComplete, this);
 *      queue.loadFile({id:"sound", src:"http://path/to/sound.mp3"});
 *      queue.loadManifest([
 *          {id: "myImage", src:"path/to/myImage.jpg"}
 *      ]);
 *      function handleComplete() {
 *          createjs.Sound.play("sound");
 *          var image = queue.getResult("myImage");
 *          document.body.appendChild(image);
 *      }
 *
 * <b>Important note on plugins:</b> Plugins must be installed <i>before</i> items are added to the queue, otherwise
 * they will not be processed, even if the load has not actually kicked off yet. Plugin functionality is handled when
 * the items are added to the LoadQueue.
 *
 * <h4>Browser Support</h4>
 * PreloadJS is partially supported in all browsers, and fully supported in all modern browsers. Known exceptions:
 * <ul><li>XHR loading of any content will not work in many older browsers (See a matrix here: <a href="http://caniuse.com/xhr2">http://caniuse.com/xhr2</a>).
 *      In many cases, you can fall back on tag loading (images, audio, CSS, scripts, SVG, and JSONP). Text and
 *      WebAudio will only work with XHR.</li>
 *      <li>Some formats have poor support for complete events in IE 6, 7, and 8 (SVG, tag loading of scripts, XML/JSON)</li>
 *      <li>Opera has poor support for SVG loading with XHR</li>
 *      <li>CSS loading in Android and Safari will not work with tags (currently, a workaround is in progress)</li>
 * </li>
 *

	/**
	 * The LoadQueue class is the main API for preloading content. LoadQueue is a load manager, which maintains
	 * a single file, or a queue of files.
	 *
	 * <b>Creating a Queue</b><br />
	 * To use LoadQueue, create a LoadQueue instance. If you want to force tag loading where possible, set the useXHR
	 * argument to false.
	 *
	 *      var queue = new createjs.LoadQueue(true);
	 *
	 * <b>Listening for Events</b><br />
	 * Add any listeners you want to the queue. Since PreloadJS 0.3.0, the {{#crossLink "EventDispatcher"}}{{/crossLink}}
	 * lets you add as many listeners as you want for events. You can subscribe to complete, error, fileload, progress,
	 * and fileprogress.
	 *
	 *      queue.on("fileload", handleFileLoad, this);
	 *      queue.on("complete", handleComplete, this);
	 *
	 * <b>Adding files and manifests</b><br />
	 * Add files you want to load using {{#crossLink "LoadQueue/loadFile"}}{{/crossLink}} or add multiple files at a
	 * time using {{#crossLink "LoadQueue/loadManifest"}}{{/crossLink}}. Files are appended to the queue, so you can use
	 * these methods as many times as you like, whenever you like.
	 *
	 *      queue.loadFile("filePath/file.jpg");
	 *      queue.loadFile({id:"image", src:"filePath/file.jpg"});
	 *      queue.loadManifest(["filePath/file.jpg", {id:"image", src:"filePath/file.jpg"}];
	 *
	 * If you pass <code>false</code> as the second parameter, the queue will not immediately load the files (unless it
	 * has already been started). Call the {{#crossLink "AbstractLoader/load"}}{{/crossLink}} method to begin a paused queue.
	 * Note that a paused queue will automatically resume when new files are added to it.
	 *
	 *      queue.load();
	 *
	 * <b>File Types</b><br />
	 * The file type of a manifest item is auto-determined by the file extension. The pattern matching in PreloadJS
	 * should handle the majority of standard file and url formats, and works with common file extensions. If you have
	 * either a non-standard file extension, or are serving the file using a proxy script, then you can pass in a
	 * <code>type</code> property with any manifest item.
	 *
	 *      queue.loadFile({src:"path/to/myFile.mp3x", type:createjs.LoadQueue.SOUND});
	 *
	 *      // Note that PreloadJS will not read a file extension from the query string
	 *      queue.loadFile({src:"http://server.com/proxy?file=image.jpg"}, type:createjs.LoadQueue.IMAGE});
	 *
	 * Supported types include:
	 * <ul>
	 *     <li>createjs.LoadQueue.BINARY (Raw binary data via XHR)</li>
	 *     <li>createjs.LoadQueue.CSS (CSS files)</li>
	 *     <li>createjs.LoadQueue.IMAGE (Common image formats)</li>
	 *     <li>createjs.LoadQueue.JAVASCRIPT (JavaScript files)</li>
	 *     <li>createjs.LoadQueue.JSON (JSON data)</li>
	 *     <li>createjs.LoadQueue.JSONP (JSON files cross-domain)</li>
	 *     <li>createjs.LoadQueue.MANIFEST (A list of files to load in JSON format, see {{#crossLink "LoadQueue/MANIFEST:property"}}{{/crossLink}} )</li>
	 *     <li>createjs.LoadQueue.SOUND (Audio file formats)</li>
	 *     <li>createjs.LoadQueue.SVG (SVG files)</li>
	 *     <li>createjs.LoadQueue.TEXT (Text files - XHR only)</li>
	 *     <li>createjs.LoadQueue.XML (XML data)</li>
	 * </ul>
	 *
	 * <b>Handling Results</b><br />
	 * When a file is finished downloading, a "fileload" event is dispatched. In an example above, there is an event
	 * listener snippet for fileload. Loaded files are always an object that can be used immediately, including:
	 * <ul>
	  *     <li>Image: An &lt;img /&gt; tag</li>
	  *     <li>Audio: An &lt;audio /&gt; tag</a>

	 * Raw loaded content can be accessed using the <code>rawResult</code> property of the <code>fileload</code> event,

	 * <b>Plugins</b><br />
	 * LoadQueue has a simple plugin architecture to help process and preload content. For example, to preload audio,
	 * make sure to install the <a href="http://soundjs.com">SoundJS</a> Sound class, which will help preload HTML
	 * audio, Flash audio, and WebAudio files. This should be installed <b>before</b> loading any audio files.
	 *
	 *      queue.installPlugin(createjs.Sound);
	 *
	 * <h4>Known Browser Issues</h4>
	 * <ul>
	 *     <li>Browsers without audio support can not load audio files.</li>
	 *     <li>Safari on Mac OS X can only play HTML audio if QuickTime is installed</li>
	 *     <li>HTML Audio tags will only download until their <code>canPlayThrough</code> event is fired. Browsers other
	 *     than Chrome will continue to download in the background.</li>
	 *     <li>When loading scripts using tags, they are automatically added to the document.</li>
	 *     <li>Scripts loaded via XHR may not be properly inspectable with browser tools.</li>
	 *     <li>IE6 and IE7 (and some other browsers) may not be able to load XML, Text, or JSON, since they require
	 *     XHR to work.</li>
	 *     <li>Content loaded via tags will not show progress, and will continue to download in the background when
	 *     canceled, although no events will be dispatched.</li>
	 * </ul>
	 *
	 * @class LoadQueue
	 * @param {Boolean} [useXHR=true] Determines whether the preload instance will favor loading with XHR (XML HTTP Requests),
	 * or HTML tags. When this is <code>false</code>, LoadQueue will use tag loading when possible, and fall back on XHR
