Subject: When calling osNpcMoveTo(), rotate the avatar in the direction of
travel.
This stops the npc walking backwards if the target is directly behind.
This means that the npc no longer returns to its original rotation once movement has finished.
If you want this behaviour, please store and reset the original rotation after movement.
This is somewhat to address http://opensimulator.org/mantis/view.php?id=5678
