Comment 1 for bug 1400075

I stumbled across this addMove a few times when working on the collider and other things but I never understood clearly what it was supposed to do. Not sure it has ever been completely implemented, Vaclav could tell maybe.

I would suggest to remove all of it if it doesn't work. "b.vel=" is good enough to impose a displacement, I don't think we need anything else. It is also a bit strange to impose a displacement through the force container.
