Fixed some typos and notations
Found an alternative to exposing BuildableBitmapTextureAtlas.getBitmapTextureFormat()
You no longer need to apply the patch to expose it
Mage the loading of a saved imask more general purpose: now you can pass a factory to generate your personal implementation of IPixelPerfectMask
Removed the dependance to Android and AndEngine from the core code: the checking.
The saving/loading of the Masks now requires a File as argument instead of creating one from a given path
Moved the core part of the checking to another project
Added the glue code to make it work with the other project
Added a few comments
Resolved conflict after packages where moved in the CollisionCoreProject
Moved the directory of the project
Changed some pakages and updated references to the new pakages in CollisionCore library
