* Single Attachments now work from inventory. You can attach from inventory and detach from inventory.

* Detaching from right clicking in world, detaches to your inventory.
* If you go up to a prim and attach it from in world, it appears in your inventory.
* Attachment placement is saved when you detach them. 
* Choosing wear remembers your last attachment point from inventory.
* Wrote a method to update an inventory item's asset and sends the updated inventory item to the Client
* Wrote a recursive method to find the folder of a known existing inventory item.
* Removed a block on physics object position on creation.  This might crash a region or two, let us know via Mantis if your region crashes because of a physics out of bounds error.
* Drop doesn't work.  The menu item doesn't even come up.  Don't know why :P.
