mandos-monitor: Bug fix: Make Ctrl-L actually redraw the screen.

* mandos-monitor (UserInterface.process_input): Bug fix: Look for key
                                                "ctrl l", not "\f".
                                                Also, add call to
                                                "self.screen.clear()"
                                                in order to actually
                                                force repainting.
