Automate Firefox JACK mapping

Previously was doing 'by hand' (with LADISH), and each new connexion was associated to a special track in Non-Mixer. This was limiting, e.g. one tab = one channel in Non-Mixer, created manually. Now with jack-matchmaker, a regexp tells that all Firefox output goes into one channel in Non-Mixer. No need to mix each tab because usually, players have an individual volume control.
