Hardhats and Rig helmets now properly update their mob icons when toggled with the action buttons (buttons on the top-left of the screen.)

Items equipped with the 'equip' button now update the player's hands. Unfortunately since the procs it uses forces an update_icons() call, using the equip button will now call it twice.
