Title: Simplify CCPhysicsNode

No need to override nodeToParentTransform completely only ensure
that position and rotation are up-to-date before performing normal
CCNode::nodeToParentTransform.

This change reduces the ammount of cocos2dx and box2d specific code
significantly.

Tested with TestCpp in box2d and chipmunk configuration.
