Big cleanup of GeniComponent stuff. Moved Resolve() into GeniComponent
since it has to be aware of the CM version. Add a Version() call to GeniAuthority with goes asks the CM what version it is exporting. Based on that, we know how to do a resolve of a component. Refactored the code that was used in GeniAggregate when creating tunnels, since that is where we have to Resolve components. This also turns up in cooked mode. Continuine moving towards a urn-only world. If a GeniAuthority or a GeniComponent does not have the URN set locally in the DB, go back to the clearinghouse and get it. Error if it is not known, and go bang on the remote site to update and rerun register_resources.
