Title: bugfix: prevent double-calling collision handlers

Problem:
If two bodies that had registered collision handlers collided,
each of their handlers would get called twice.

This is because RNPhysics.LocalCollisionHandling already gets
called for each body involved in the collision. Therefore,
it should only call the handler for body1, and *not* for body2.
