implement aggregate_locking design
Now aggregation will not lock the wiki. Any changes made during aggregaton are merged in with the changed state accumulated while aggregating. A separate lock file prevents multiple concurrent aggregators. Garbage collection of orphaned guids is much improved. loadstate() is only called once per process, so tricky support for reloading wiki state is not needed. (Tested fairly thuroughly.)
