859 * The semantic prior this change was: trigger if something has moved on or off

861 * checker with a matching item, has it, activates the connection, throws the item

865 * Wed Jan 10 11:34:26 CET 2007 elmex: fixed this function, we now check
866 * whether op is on this mapspace or not, because the value (1|0) depends
867 * on this information. also make sure to only push_button if op has
868 * a matching item (because when we do a push_button with value=0 timed gates
