Subject: * 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.
