Subject: Use chode character actor.SetMomentum() to force full restore
 Velocity in scenepresence TeleportWithMomentum(), since actor.Velocity was
 selected by original coders as the input of a desired velocity (even
 'forces') that is modified by character conditions, like not changing 
 velocity.Z if it is in free fall.
