Re-add gang and conspiracy to secret

[UrsulaMejor]

I've started my own private miscreant gang the Tunnel Snakes as an assistant during a few rounds. We had a secret base in the maintenance tunnels and mugged people with knives and wore matching black jumpsuits.

If you want a miscreant gang during regular rounds, try starting one!!

Other than that, I don't think either gang or conspiracy is much fun as-is and they need some work if we're gonna put them back into rotation
