This fixes a bug where the animations in MultiWaveView were keeping references to bitmaps and preventing them from being reclaimed during GC. The solution is two-fold: 1. When any given animation completes, it is now removed from the list of running animators objects. 2. When the client explicitly calls reset(), we release all references to animators and objects.
