1.0.1: get along with KodiMov+

- Channel numbers: 1.0.0 set "use channel numbers from backend" before
  "always", which Kodi refuses with more than one PVR instance loaded, and
  wrote its marker anyway. Now it checks every 5 minutes: if the setting is
  hidden it turns "always" on, and it turns the setting on once (new marker
  numbers-on, so existing installs get one proper pass). It never turns
  anything off, and turning it off by hand afterwards is respected.
- Takes turns with KodiMov+ to restart IPTV Simple, through the
  pvr.iptvsimple.restarting property of Kodi's home window.

+## Living with KodiMov+
+
+Both add-ons keep an instance of IPTV Simple, and share two things in Kodi:
+
+- **Channel numbers.** Kodi only lets *Use channel numbers from backend* be
+  changed while it applies: with one PVR instance loaded, or with several and
+  *always* on. So which add-on came first changed the result. Both add-ons
+  now check it every few minutes: if the setting is hidden they turn *always*
+  on, and they turn the setting itself on once. Neither ever turns anything
+  off, and once it has been on, turning it off by hand is respected.
+- **Restarting IPTV Simple** restarts every instance. Each add-on does it only
+  when nothing is playing, and they take turns through a property of Kodi's
+  home window (`pvr.iptvsimple.restarting`).
