Fixed bugs with timeScale.
Fixed clearAnimation(int) crash.
Renamed clearAnimation to clearTracks.

Alternate Atlas constructor.
Scale bounding boxes on load.
Allow latest JSON format to be loaded.
Better Corona examples.
Removed non-uniform scale from dragon for Corona.
Fixed spine-unity, spine-tk2d.
Fixed event timeline missing first event.
Changed when events are fired.

Events are now fired from lastTime (exclusive) to time (inclusive). This allows an event at the end of an animation to be fired before the next animation starts. The "complete" callback will happen before the event though, because "complete" happens in update() and events are triggered in apply().

Note events are not fired for the previous animation during mixing (crossfading).
Fixed first event not getting fired.

Damn this is hard to get exactly right!
Fixed ("fixed") Android rendering, #33.
Additive blending for cocos2d and cocos2dx.
