Made it so auto- and admin-ERT crosscheck each other

This avoids having an admin call an ERT and then having the auto call
a second ERT on its own

Also added a check to abort ERT if not enough people sign up (members_required is currently 1)

Fixed a few small issues with admin-ERT

* ERTs will no longer show up as "unknown" in the traitor panel, deadchat, and at the end of the round, among other places.
* Added update_icons() -> You no longer need to trigger it manually by clicking something
