    - the ownership of the locked objects is transfered to the player who
    rented the apartment.

  Version: 1.3 
  Autor:   Sokomine
  Date:    12.02.14
--]]    

-- Changelog:
-- 15.06.14 Added abm to turn apartment:apartment into either apartment:apartment_free or apartment:apartment_occupied
--          so that it becomes visible weather an apartment is free or not 
-- 15.05.14 Added diffrent panel for occupied apartments. Added textures created by VanessaE.
-- 24.02.14 Buildings can now be removed again (dig the spawn chest)
-- 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.
--          Introduced diffrent categories so that i.e. a shop and an apartment can be rented at the same time.
-- 16.02.14 Removed MAX_LIGHT var and set to fixed value.
-- 16.02.14 Only descriptions and ownership of known objects are changed.
--          When digging the panel, the descriptions are reset.
-- 14.02.14 Improved formspecs, messages and descriptions of rented and vacant items.
--          Players with the apartment_unrent priv can now throw other players out of apartments. 
--          Apartment names have to be uniq.
--          Each player can only rent one apartment at a time.
--          Added /aphome command
