    call-window: allow user to enter dtmf events using his keyboard
    
    Ideally we should stop sending the DTMF event when the key is released but we
    can't easily do that in Gtk+; we'll have to write our own widget.
    I'm going to give it a shot but this is already a nice improvement so we
    shouldn't block on it.
