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

There's an outlet on the east wall near the cafe counter, about 6 feet off
the ground. It has "NEVER UNPLUG" written on it in marker. The entire door
system is powered by an orange extension cord which leads to this outlet.
The end of this cord used to be three-prong but somebody knocked the third
prong off, so it doesn't stay put, and every time it falls out even a
little bit, the door system and camera get powered off. I covered the whole
thing in duct tape before I left last night so hopefully that won't be a
problem anymore.

I hate working with the door system code because the execution environment,
and basically that whole server, is a mess which makes me feel frustrated
every time I deal with it. That machine is also acting as our router, and
the entire Omni network is running without a firewall because nobody else
wants to deal with it either. I would be very interested in setting up a
new relatively low-power machine to be the router and reassigning this one
to just be a shell server. Then that can give us more flexibility to
overhaul it without causing network downtime.

If somebody can find and set up the new hardware i can take care of
everything else. All it would need is a few gigs of disk space and at least
2 ethernet ports.
