refactor: Make AttachmentModulesTests.TestSameSimulatorNeighbouringRegionsTeleportV2 use already available TestClient handle rather than retrieving it via the ScenePresence
Add TestSameSimulatorNeighbouringRegionsV2() regression test for v2 entity transfer protocl
Add ScenePresenceTeleportTests.TestSameSimulatorIsolatedRegionsV2() regression test for v2 transfers.

Also adjusts names of teleport setup helpers in EntityTransferHelpers
Fix issues with RemoteAdmin admin_save_heightmap and admin_load_heightmap not working.

This is because they were wrongly looking for both regionid and region_id parameters in the same request.
Now only region_id is required (and recognized), regionid having been already deprecated for some time.
This is essentially Michelle Argus' patch from http://opensimulator.org/mantis/view.php?id=6737 but with tabs replaced with spaces.
Thanks!

Allow updating the wearable type of wearables that have a type of 0.
This will allow viewers to fix broken wearables as they detect them.
Show number of connections each bot has established in "show bots" command.
Merge branch 'master' of ssh://opensimulator.org/var/git/opensim
Create a separate pCampbot "disconnect" console command which disconnects connected bots.

"quit" console command now requires bots to be separate disconnected first before quitting.
This is to prepare the way for disconnecting/reconnecting different numbers of bots in a pCampbot session.
And hopefully resolves bug where console appears not to be reset if Environment.Exit(0) is called on a different thread
Make it possible to disconnected a specified number of bots via the pCampbot console command "disconnect [<n>]"

Bots disconnected are ascending from last in numeric order.
Temporarily no way to reconnect bots.
refactor: restructure pCampbot multi-bot connection code.
refactor: start bot connection thread within BotManager rather than externally
Make it possible to reconnect pCampbots with the console command "connect [<n>]".

If no n is given then all available bots are connected
