Fixed attachment changes.
Refactoring to make it easier to load a SkeletonData in a subclass constructor.
Fixed scale.
Minor updates.
Fixed static methods.
Clean up.
AS3 and Starling runtimes.
Fixed spine-starling rendering.
Better getBounds.
Fixed rootBone.
Brought back some convenience methods.

Anything more than this and you have to use the C API!
Organized and simplified spine-starling.
Added Atlas and Flash rendering to spine-as3.
Fixed slot alpha blending in spine-unity.
Refactoring: RegionAttachment vertices, texture->rendererObject...

- Vertices are no longer stored on RegionAttachment. The vertices are temporary state, not part of RegionAttachment's persistent state like UVs and offset.
- AtlasPage and RegionAttachment "texture" field is renamed to "rendererObject". This is a better name as it may not be a texture.
- AtlasAttachmentLoader uses the AtlasRegion as the rendererObject. This enables a renderer to use region information if needed. The page rendererObject is still available.
- Better "enum" look up for AS3.
- Unity4 example doesn't use a compressed material.
Refactoring: changed references to "bind pose" to "setup pose".

This better matches "setup mode" in the editor and we can be consistent in code and docs from now on.
Better JSON code.
JavaScript runtime.

Untested and there is no rendering.
Forgot to check in cocos2d-iphone refactoring!
Fixed flip x/y for root bone.
