Code Review for Job #19484
Re-enabling particle-avatar collisions.
Cleanup of "soft hand paddle" collision hackery.  Still a hack, but more commented and readable.
Hand now holds a ball a bit forward, which prevents the body from colliding with the ball on throw.
Removing menu option for where to hold the ball -- we always hold from the finger tip (approximately).
