* Apply http://opensimulator.org/mantis/view.php?id=3142

* Changes varchar(36) columns to UUID type in MSSQL - this will be much more efficient
* ===As always, please, please backup your database before applying this patch===
* Thanks Ruud Lathrop (for the patch) and StrawberryFride (for the review)
