This fixes issue #578
Fixes issues #573 and #574
Made further changes to the find command as per #573 and #574, making alias-query aware of low-high dbref limits and changed room/exit/char filters to use inherits_from instead of dumbly assuming e.g. a room being an object with no location. Also restructured the code a little.
