Update fan-out signal

Browse Source 
* Signals use camelcase.
* use a static signal, independent of the route

Previously the signal was handled by RouteUI, which
caused various issues:
 * the RouteUI may not yet be available
 * There may be many RouteUIs for a single Route
   (mixer, editor-mixer, meter-bridge strips)
