[Build] Doorbell "fixed", computer gate control and keypad need some love.

Thanks for working on this Asheem. I am not able to trace this problem
to anything in the software on minotaur. Certainly we have never seen
this new unexpected "fail open" mode, where the lock is stuck open and
the buzzing won't stop until you hit the doorbell again. We need to
get together and go over the new wiring ASAP, as this is going to be
very annoying for people.

I am also not opposed to disconnecting the doorbell until this
annoying effect is fixed. AFAICT the keypad is working fine now.

In short, either this is a problem with the new wiring, or two wires
got shorted which we didn't know about until the new wiring exposed
the problem, or some other weird interaction between the wiring and
the rest of the system.

As far as resetting the keypad server: we noticed the server can go
bad after running several hours. Last night I put in a cron job to
restart it hourly, and (knock on wood) have seen no problems since
then. I am working on the root cause analysis, but in the meantime you
can reset the server on minotaur if needed by calling
/home/jesse/bounce-gate

If you don't have an account on minotaur, you can also restart it with
this secret URL:
