Distinguish between running relays and non-running relays which last had the Running flag
Lunar was rightly confused by relays having the Running flag but which had a Running field of false. The Running field is true iff the relay is contained in the last known network status, whereas a relay could have had the Running flag when it was last listed in a network status. So, this case is technically correct, but it's highly confusing. I wonder if we can improve Atlas' UI to make it clearer that the Running field is what most people will be interested in.
