* A tweak of the caps system so that new caps have random paths instead of a fixed path

* This allows caps requests to be routed to regions where the agent is currently a root agent instead of the region that they logged into as it did previously.   
* This fixes a wide variety of bugs related to 'can't do X once i've crossed a border'.
* The first seed cap request fails, the second one works.  (this generates an error message on the console)
* Experimental.
