Subject: BulletSim: include check for volume detect in check for zeroing
 avatar motion.

Normally, avatar motion is zeroed if colliding with a stationary object so
they don't slide down hills and such. Without volume detect check this also
allowed avatars to stand on volume detect objects and to have some jiggling
when they were in the volume detect object. This commit fixes both.
