* Fixes mantis http://opensimulator.org/mantis/view.php?id=4044. Turns out folders were never being removed from trash when they were singled out for purging in trash. They were being removed when Trash was purged as a whole. That behavior is now fixed for the new InventoryService set.

* Removed left-overs from AssetInventoryServer.
