well, wowsers that was quick. already seems to be working, test relay is full up with events from my follows. gonna deploy this on the test

it does a one time sync, has a marker for that, when it's done, so it doesn't do it again, and then it does a default hourly sync of the last two hours of events to catch everything, so if it's your personal relay it keeps all your relevant messages to see what's happening in your circle. which i think is also a nice thing for a paid relay to do as well.
