-Trigger shapes removed in 2D, they became obsolete long ago when areas could detect their own overlap

-Added ability to disable individual collisionshape/polygon
-Moved One Way Collision to shape, allowing more flexibility
-Changed internals of CollisionObject, shapes are generated from child nodes on the fly, not stored inside any longer.
-Modifying a CollisionPolygon2D on the fly now works, it can even be animated.

Will port this to 3D once well tested. Have fun!
