Update information in StandaloneCommon.ini.example to reflect this
Remove ISharedRegionModule interfaces from all SimianGrid connector classes temporarily since this stopped standalone from working (due to absence of AssetURI settings, etc.).
Solution here may be to create separate region module connectors as done by local/grid/hypergrid so that loading can be controlled via include files
Or otherwise work out how to stop these modules from being loaded for all OpenSim invocations
Adds MockUserAccountService and connects it up
Stops services being carried over between tests since this leads to hard to find bugs
Improves information and error reporting when loading plugins
