[ODE] Damage!

[Erwin de Vries]

Or even better just provide a callback function for these things. Just some
thoughts..

Provide a function:
void ImpulseCallback(dBodyID Body, dVector Pos, dVector Normal, dReal
Impulse)

The normal and Impulse members could also be a combined in a Impulse vector.

It might also be a good idea to simply provide a once per step resultant
impulse callback instead of 1 per contact point. Or provide both. =P
