* If an orphaned group is found in the mysql or mssql databases (i.e. there is no prim where UUID = SceneGroupID), then force one prim to have UUID = SceneGroupID.

* A warning is posted about this on startup giving the location of the object
* This should allow one class of persistently undeletable prims to be removed
* This change should not cause any issues, but I still suggest that you backup your database beforehand
* If this doesn't work for previously linked objects, then you could also try the workaround in http://opensimulator.org/mantis/view.php?id=3059
* This change has been made to mysql and mssql, but sqlite appears to work in a different way
