schedule stop DECAY in the future for firefox 
Firefox at this time cannot smoothly schedule audio parameter changes
to happen immediately. Immediately scheduled changes clip when firefox
tries to catch up. Smoothly fading out a sound immediately instead of
clipping the end of the sound, in firefox at this time clips the sound
between where the fade out starts and where firefox catches up and
finishes the scheduled fade.

d40564d61a make EffectChain standalone 
- EffectChain knows of audioEngine so it can create Effects
- EffectChain connects to the target specified by .connect(target)
- EffectChain can connect to other Effects or EffectChains
- EffectChain can clone itself and connect to the original's target
- Add EffectChain.update to mirror Effects API
- Use deepest setting first in setEffectsFromTarget

e1d478244d audioengine loads sounds indexed by md5 
audioplayers store list of their own active sound players indexed by md5 of the sound. sound players are created when the sound is played, deleted when it ends, and removed from the list of active sound players. the pitch effect uses this list of active sound players to set their playback ratios.
