Add pCampbot "show bot" console command to show more detailed information on a particular bot (e.g. what sims they are connected to)
Fix build break from last commit a3e1b27 on mono 2.4.3

Looks like this level of mono doesn't have a string.Join() which will take a list rather than an array (or some implicit conversion isn't happening)
* Fix some threading issues in BulletXNA (the managed bullet library), this should better allow you to run it in multiple region scenarios (but why would you really want to do that?)  Source in OpenSimLibs.
* Fixed a null ref during shutdown.
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.
