* Implment task inventory item asset update for the old non CAPS transaction system

* This means that saving notecards in prim inventories should now work.
* Not the nicest code in the world - the transactions system is pretty fugly right now
* PLEASE NOTE: Currently, the prim will not repersist until up to 15 seconds after it is unselected.
* What we really need is a proper mechanism so that any prim updates still waiting when the simulator is quit are performed before exit.
