 -- Changelog:
+-- 25.02.14 Buildings can now be saved. Just prefix the apartment name with save_as_
+--          start_pos and end_pos of apartments are now saved (necessary for the above mentioned save function).
+--          Building spawner chest is now working.
 -- 22.02.14 Added code for spawning several apartments at the same time. 
 -- 18.02.14 Added support for further nodes (shops, travelnet, ..).
 --          Cleaned up formspec that contains apartment information.
