The F3 coords manager is blocked if you're not an admin. This check happened even when playing a replay, where you actually aren't. There's now a check to make sure you are actually server-connected-to-game before running the logic.
Also moved it to a manager because this *shouldn't be a bloody entity system in the first place*.
