MIDI alarm when the Lighting PC drops out of NA Tracks' session (FX lights)

Browse Source 
Tracks sends the FX lighting cues to the Lighting PC through NA Tracks'
network MIDI session. A midi_peer check may now name a "host": the watchdog
reads that Mac's sessions over SSH every 5 s, sending this folder's
coremidi.py over stdin (nothing installed there). Unreachable = no verdict;
the Tracks Mac's own ping check covers that.
