Fix (add) ability to rez objects by dragging them out of another prim's inventory.

This should happen if the client supplies a task ID with the RezObject call.
The rez goes through the same code as llRezObject(), so the same perms are applied.
Rotation isn't yet preserved, this should be fixed shortly.
