[sudo-access] let's fix sudobot to warn us when omnidoor is down

so I don't know what happened before I arrived, except that yar said
"i fixed it by plugging it in" and I don't know what exactly that means, and i
would like to know exactly.

anyway, when I got there the beaglebone black was somehow powered off (no LEDS)
but it had 5v being supplied to it.  I have no idea what caused that.

i power cycled the beaglebone black AND the USB hub's power source (which is
separate) and then everything worked.  Someone should install a button in the
cabinet to do a reset like that.  for some reason, when the BBB and USB hub are
not both power cycled, it can lead to a situation where the doorjam program
doesn't connect to the magstripe reader and everyone is unhappy.

it would have been nice if sudobot had alerted us to the fact that it was not
hearing back from the front door computer, but i think that functionality has
been disabled?  I can't tell why it doesn't work.

fixing the bot, so it alerts us when there is a problem, should be our next
step toward higher reliability of the front door system.

does anyone volunteer to do that?  it's running on the sudoroom server (in the
building) under its own username, using psy as a process manager.
