Watch the DiGiCo FOH console inside AUDIO; "+ Key" asks for a group when the deck is full

- DIGICO (in the AUDIO group): Companion's DiGiCo_FOH connection, the digico-relay helper on
  NA Ingest (hold AUDIO restarts it), and a ping to the console at 10.1.60.100 (the OSC
  connection reads good even with the console off).
- Settings page: "+ Key" on an unwatched Companion connection asks which group key to put it
  in when the Status page has no free spot (it used to make a key nobody could see); the
  connection field of a check suggests Companion's connection names.
