This integrates the OpenSim refactoring to make physics, etc into modules.
AVN physics hasn't been moved to new location.
Does not compile yet.
Merge branch 'osmaster' into mbworknew1
Move the experimental extra features functionality into the GridService. This sends default values for map, search and destination guide, plus ExportSupported control to the region on startup. Please watch http://opensimulator.org/wiki/SimulatorFeatures_Extras for changes and documentation.
This requires a new GridService.GetDefaultHypergridRegions() so ROBUST services require updating but not simulators.
This method still returns regions flagged with just DefaultRegion after any DefaultHGRegions, so if no DefaultHGRegions are specified
then existing configured defaults will still work.
Immediate use is for conference where we need to be able to specify different defaults
However, this is also generally useful to send experienced HG users to one default location and local users whose specified region fails (e.g. no "home" or "last") to another.
This is usually because the file name was singular (*Service*) but the class name was plural (*Services*).
This is to make configuration easier rather than having to look in the c# code itself to find the slightly different name of the connector.
This does not affect existing configuration since the files are being renamed rather than the classes.
