Remove shop steal prompt for L18+ Thiefs
The wiki notes that L18+ Thief power of robbing shops is "[f]airly annoying since it adds a prompt every time an item is picked up in a store". Just having gone through the Casino, I can definitely confirm this. It should be removed and the ability to steal from shops should be implemented in a different way (perhaps from the Ctrl-x screen, or as a toggle [also possibly from the Ctrl-x screen]).
