locks/shared_locked_xdoors2.lua

-- xDoors² mod by xyz
-- modified by Sokomine to allow locked doors that can only be opened/closed/dig up by the player who placed them
-- a little bit modified by addi to allow someone with the priv "opendoors" to open/close/dig all locked doors. 
-- Sokomine: modified again so that it uses the new locks-mod
