Update 7

- Fix: Drones now get assigned_role = Drone.
- Tweak: AI is no longer considered a head job for playtime system
configuration purposes.
- Tweak: Job gating (when enabled - its off by default) is based on Crew
playtime now. This is for all jobs, including heads and AI. Gating based
on department playtime is still possible, but based on a separate config
option that's also turned off by default.
