Increase the time lock for nuclear operatives and and nuclear commanders

40 is fucking absurd. On main that's 40 hours and on rp it's 60 hours. The amount of people putting 40-60 hours into this game is a hell of a lot smaller than most people realize. Roundlock it to maybe a max of 15-20. 

Mentors and HoS getting priority is also an awful idea IMO. Every time we give mentors/HoSes extra perks outside of mentoring Or HoSing, it increases the encouragement for people to apply for the wrong reasons. There's also literally no reason a mentor/HoS would be a better nukie commander than anyone else.

I also think as a general mindset we shouldn't be trying to get the most "qualified" people possible for antag rolls. A massive chunk of this game is the people side, which means people are going to be playing at their experience level, with their abilities, and we shouldn't be attempting to "fix" that. If the average nukie team can't win (which doesn't seem to really be the case anyway), we need to buff nukies, not try to find the better nukie players.

i said commanders, not normal operatives
