Build the event object. We were originally going to include taint on each one, but TS doesn’t accept / use that, so it is a waste of time.

We’ll truncate any object that isn’t important to the taint ranges of this event, so that we don’t murder TeamServer by, for instance, hypothetically sending the entire rendered HTML page >_> <_< >_>
