hxcollision 1.1.0 stable

This release adds many bug fixes and some new examples thanks to @Dvergar, documentation, and a much needed api cleanup of the code toward a more consistent reliable library.

• Added documentation and clean up of code
• Renamed Vector2D to Vector and cleaned up code to ONLY what is needed. This class is meant to be as small and easy to integrate as possible.
• Refactored for easier maintaining in embedded libraries
• Added documentation and clean up of code
• Renamed BaseShape to Shape, continued refactoring
• Renamed Collision.testShapes to Collision.test
• Renamed Collision.testShapeList to Collision.testShapes
• Renamed Collision.rayCollision to Collision.ray
• Fixed various bugs in collisions
• Fixed separation/unitVector behaviour (signs bugs)
• Fixed bug with Polygon/Polygon collisions not returning best vectors
• Fixed bug where you couldn't beginFill using OpenFLDrawer
• Fixed collisionData in CheckCircles, shape2 wasn't assigned.
• separation/unitVector is now bound to shape1
• Added 2 samples (usage2 & usage3)
• Added drawVector in OpenFLDrawer showing vector direction
• Added drawShape in ShapeDrawer, will cast proper types and call appropriate drawing functions.
