* TransformMatrix.destroy is a new method that will clear out the array and object used by a Matrix internally.
* BaseSound, and by extension WebAudioSound and HTMLAudioSound, will now emit a `destroy` event when they are destroyed (thanks @rexrainbow)
* A new property was added to the Scene config: `mapAdd` which is used to extend the default injection map of a scene instead of overwriting it (thanks @sebashwa)
* GetBounds `getTopLeft`, `getTopRight`, `getBottomLeft` and `getBottomRight` all have a new optional argument `includeParent` which will factor in all ancestor transforms to the returned point.
