Subject: [PATCH] Fix "ghost stacks" created when a player clicks an item on
 the ground: since the object is not immediately removed, any other code may
 still think an object is there, therefore leading to item duplication. This
 code therefore sets the itemstring to '' after the object is picked up to
 avoid such issues
