1.0.0+kodimov.11: Movistar's channel numbers with more than one IPTV Simple instance

- Kodi only lets "use channel numbers from backend" be read or changed while
  it applies: one PVR instance loaded, or several and "always" on. With a
  second instance (Radios de Vigo, a leftover empty one) it refused the
  setting the TV guide setup made, and numbered the channels 1, 2, 3...
- The service now checks it every 30 minutes and after the setup: if the
  setting is hidden it turns "always" on, and it turns the setting on once
  (marker file numbers-set). It never turns anything off, and turning it off
  by hand afterwards is respected. Existing setups are put right this way.
- KodiMov+ and Radios de Vigo take turns to restart IPTV Simple, through the
  pvr.iptvsimple.restarting property of Kodi's home window.
