fixes for avatar paddle-hands, plus some hackery for demo
Merge branch 'master' of ssh://github.com/highfidelity/hifi into paddle-fixes
adding back log about mismatching packet type
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).
