Don't show the ScrLPS data twice in the WebStats based statistics page.
Cleanup some unused code and configuration entries
If BulletSim is running on its own threads, start this thread via the thread watchdog.

This allows us to see the presence of the permanent thread via the "show threads" console comand.
Also adds the region name to the thread name.
minor: fix indenting from previous commit b08ab1e
Make bulletsim thread alarm if no update for 5 seconds.

The cost is minimal (also done for scene loop) at the benefit of telling us if this thread simply stops for some reason.
Don't need to check separate physics status in bulletsim update since that method is only run for an indepndent thread anyway.

Also remove bulletsim monitored thread from watchdog on shutdown.
Start long-lived thread in IRCConnector via watchdog rather than indepedently, so that it can be seen in "show threads" and stats
For processing outbound http requests in the XMLRPCModule, start the thread through Watchdog for monitoring and stat purposes.
