Don't allow users to attempt to sit on objects in a child region without going to that region first.

If this is attempted, they get a "Try moving closer.  Can't sit on object because it is not in the same region as you." message instead, which is the same as current ll grid.
Sitting on ground is okay, since viewer navigates avatar to required region first before sitting.
