Subject: * Standalone logins will now go through the sequence of "requested
 region, default region, any region" before giving up * Hip offset should have
 been added not subtracted (it's a negative offset). This puts avatar feet
 closer to the ground * Improved duplicate checking for terse updates. This
 should reduce bandwidth and walking through walls
