* Apply a modified version of http://opensimulator.org/mantis/view.php?id=2290

* This allows multiple user profile providers to be specified in OpenSim.ini separated by commas
* If multiple providers are specified then a request for a user profile will query each in turn until the profile is either found or all have been queried
* Unfortunately I don't believe this order can currently be specified, which if true is something that will need to be fixed.
* Thanks to smeans for the original patch.
