* Added transform constraint rotate, scale, and shear offsets and mixes.
* Added TransformConstraintTimeline.
* Added bone shearing.
* Added ShearTimeline.
* Changed Skeleton#updateCache.
* Changed JSON and binary formats. Some binary format fields and enums were rearranged for consistency -- sorry, but it's better for the long term. Docs for both are up to date.

Version 1 of the license didn't make sense: it required a Spine license to use the Spine Runtimes at all. This means if you used the Spine Runtimes in your application, anyone who purchased a copy of your application also needed a Spine license to use the runtimes. This was not the intent!
Version 2 of the license fixes this by allowing anyone to use the Spine Runtimes but only for internal use. When you purchase Spine, the Spine license (http://esotericsoftware.com/spine/files/license.txt) grants you the right to make and distribute derivative works of the Spine Runtimes. Now it makes sense: making and distributing applications with the Spine Runtimes requires a Spine license, but anyone can run that software without needing a Spine license.
With this fixed, I hope we never need to change the license again!
Holy refuctoring! Sorry for the change, but some libraries were having naming conflicts. You can define SPINE_SHORT_NAMES before including spine-c headers if you want to use structs and functions without the "sp" prefix, as it was before.
This has some API breakage, sorry. The new AnimationState now handles multiple "tracks", which makes it easier to apply and queue multiple animations at the same time, no longer do we need multiple AnimationStates.
