[MERGED PR] Add Janitor alert to Crisis Alerts

[Splints]

I tend to think it would be better to add a 'Custodial Services' or 'Station Cleaning' group to the default message groups. I only just learned that station repair includes janitors, and I don't think that is intuitive. I think doing both is fine too. Maybe a second PR if not included here.

I'm just not sure a player unfamiliar with the details of the crisis alert message would think to use a crisis alert to contact someone about cleaning since it isn't as dangerous as the other alert types.
