* mandos (Client.enable, Client.disable, ClientDBus.approve): Call
                    self.send_changedstate() after change, not before.
  (Client.disable): Bug fix: Handle disable_initiator_tag and
                    checker_initiator_tag of 0.
  (Client.init_checker): Bug fix: Remove old checker_initiator_tag and
                         disable_initiator_tag, if any.
  (Client.bump_timeout): Bug fix: Remove old disable_initiator_tag, if
                         any.
  (ClientDBus.Timeout_dbus_property): Bug fix: Use self.expires.
  (ClientHandler.handle): Bug fix: timedelta_to_milliseconds is a
                          global function, not a class method.
* mandos-monitor (MandosClientWidget._update_timer_callback_lock):
  Removed.  All users changed.
  (MandosClientWidget.last_checked_ok): Removed (unused).
  (MandosClientWidget.__init__): Don't call self.using_timer().
  (MandosClientWidget.property_changed): Removed unused version.
  (MandosClientWidget.using_timer): Stop using the counter
                                    self._update_timer_callback_lock;
                                    be strictly boolean.
  (MandosClientWidget.need_approval): Don't call self.using_timer().
  (MandosClientWidget.update): Call self.using_timer() throughout.
                               Bug fix: Never show negative timers.
