IE9 hacks

Browse source 
* GET params in a url sent through router.navigate are lost on IE9, use document.location.href = url instead
* Temporarily put raster images in the DOM to give them dimensions so they are rendered in the spritesheet correctly
* Add {cache: false} to fetches for /hoc course instances and sessions
