Title: Fixes bug in crossfade

Fixes bug in crossfade() when crossfading back and forth between two animations.
Added code to detect when this happens and to reset each clip's state so that it can't be fading in and out of the same clip.
Added bit mask CLIP_ALL_BITS to AnimationClip.
Fixes bug where an AnimationClip can be added multiple times to the AnimationController.
Clean up of code in play()/stop().
