Subject: * Tweaks the hard cut to apply to collisions of Greater then Normal Z
 0.95.   This fits within Ubit's framework of multi-body collisions, just
 moves the reactive force to the Midboxgeom(actual detection) instead of the
 bigbox geom(pre detection)

Subject: * This fixes the avatar stuck in objects on login and teleport by
 gently applying an upward motion when stuck in things on the Z * Comments
 describe how it filters out good, normal collisions, from 'stuck'
 collisions..   It's especially sensitive in feetbox collisions since this is
 where normal collisions happen under usual circumstances.
