Zefram 46d44eebcf Refactor deployer and dispenser
Merge implementations into a single "wielder" mechanism.  Clean up the
code a bit.  Fix get_player_control_bits for the dispenser (it wasn't
indicating the sneak setting).  Fix drops for dispenser (dispenser_on was
dropping as itself).  Show item image, as well as name, at head of form.
