Added a setting to [Startup] section of config that will allow the simulator to start up with no regions configured.

I added the boolean config setting "allow_regionless", defaulting to false. If set to true, opensim will start up ok if no region configurations are found in the specified region_info_source. It will not ask the user to create a region.
