* Implement basic region filtering as described in https://lists.berlios.de/pipermail/opensim-dev/2008-November/003468.html 

* This is done by sending a 'major interface version' number on sim registration.  Developers must increment this every time they make a change that would make the previous 
OpenSim revision failure incompatible with the new one (non-fatal incompatibilities are fine).
* This number resides in OpenSim.Framework.Servers.VersionInfo.MajorInterfaceVersion
* This allows the grid service to stop older, incompatible regions from connecting
