* Implements Extensions to MRM. This allows Region Modules to insert new classes into OpenSim MRM's.

* Example in region module:
    Scene.GetModuleInterface<IMRMModule>.RegisterExtension<IMyInterface>(this);
* In the MRM:
    //@DEPENDS:MyExtensionModule.dll
    ...
    Host.Extensions<IMyInterface>.DoStuff();
