Don't require GM status for check/contest

[rozzingit]

This was discussed on channel at the time the new check system came out, and Apos agreed (IIRC) that it was probably best. check/contest is actually plenty useful for non-GMed scenes, either events or just regular RP, and encouraging event runners who aren't GMing to just set themselves as GM for a cal event is a bad idea, as staff has specifically had to discourage that in the past because of people setting themselves as a GM and soliciting GM RS for events they are ICly running but that aren't PRPs they're GMing.

Basically, probably better for check/contest and check/contest/here to just not require a GM status. (And deal with anyone trying to spam it or something by telling the individuals to knock it off.)

I just didn't notice until today that it wasn't adjusted at the time and there wasn't an outstanding issue for it, so I'm recording it here so it doesn't get forgotten.

Although I'll be changing the mechanics of how checks work, check/contest will still be maintained in some form, so this feature still works for Hacktoberfest
