* First draft resolution of mantis 777, 734, 389 - scripts do not save in non-home regions

* Should work in multi-region standalone and grid modes
* This should also solve other non-home region caps issues (map requests, RC client inventory requests, etc)
* We now pass CAPS information on to the destination region on region crossing, and set up a CAPS object when an agent becomes a master
* Current limitation is that this will only work if your http_listener_port is 9000
* This is a very early code cut (lots of bad practice, hard coding and inefficiency).  However, I wanted to get this out there for feedback and my own sanity.  Next few patches will clean up the mess.
