* Exprimental prim inventory persistence can now be enabled by users.

* This can be turned on by setting storage_prim_inventories_experimental = True in OpenSim.ini
* Implemented for sqlite and MySQL, no MSSQL implementation yet
* As an experimental feature, there is no guarantee that this won't take down your region or that the db representation won't need to change.
* More (and continuing) details at http://opensimulator.org/wiki/OpenSim:Prim_Inventory_Persistence
