Tooltron status indicator
There should be some way of indicating if tooltron is working. There should be something on the website and a physical LED or something on the cardbox or nearby to indicate if the system is up and running.
If tooltron is stopped using the daemon, this should be reflected using this system. There could also be some kind of periodic signal or something sent to the cardbox that tells people tooltron is alive.
We need this so people can tell the difference between not having access and tooltron being down, also in case its down due to maintenance (like reprogramming one of the tools).
