Updated group collision to occur prior to entity collision so entities have potential movement from their carrier incorporated into their movement.
Removed .collisionUnresolved property from colliding entities and maintain a separate non-collider list.
Collision group internal restructuring.
Separated collision-group into two components since entity groups (like moving platforms) and the overall world group had such divergent code. The world group is instantiated by adding a handler-collision component on a scene layer.
Fixed regX and regY from owner for collision-basic and made sure example game works with new collision code.
