[Opensim-dev] Reducing the plugin mechanisms

[Diva Canto]

FYI there's now a branch called physmodules that has this work.We'll 
have it under testing for some more time, and if no major issues arise, 
we'll merge it.

Essentially, all new server-side physics should now be provided as a 
region module (INonSharedRegionModule) that also extends PhysicsScene. 
See all OpenSim.Region.PhysicsModule.* sub-projects for how to do it. As 
region modules, the corresponding dlls need the mono addin declarations 
usually placed in AssemblyInfo.cs.
