Fixed timeScale initial value.
Animation state example for SFML to match other runtimes.
Fixed issue #22.
Stupid Xcode and its space indentation!
Atlas now prefixes images referenced in the atlas file with the directory containing the atlas file.
Removed junk that shouldn't have been committed. :(
Fixed skins and color/image timelines.
Slots and bones start in bind pose.
Explicit casts.
Changed Spine export format.

There are no longer separate animation files, they are now inside the skeleton file. This means there is just one file to manage, which is cleaner. Now that animations are stored in SkeletonData, they can be looked up by name which leads to cleaner runtime APIs.

cocos2d and cocos2d-x runtimes got a cleaner ObjC/C++ API.
