Qt: support digit chars as menu group accelerators

Have Qt catch up with tty and X11:  in a menu, when not already
entering a count and player types a digit, check whether it is the
group accelerator for any of the menu entries.  If so, toggle their
selection state; if not, begin counting for the next item the player
eventually picks.
