* First draft implementation of copying prim inventory items back to agent inventory

* Now, if you own an item in a prim, you should be able to successfully drag it back into your inventory
* Temporarily, users which are not owners of the item cannot copy it, even if 'everyone can copy' is set
* This is pending fixes/implementation of upstream permission implementation
