- Added a better lobby ready system
- Added a check to see if the round has started so you can't ready up while the round is in the preround phase after the timer hits 0
- Added a crew manifest from bay viewable from the lobby and as a ghost so you can decide what you want to do based on a more visible departmental population.
- Did not include the 'active/inactive' part of this, which checks if people are braindead/catatonic, because I don't think our server has long enough rounds for that to be a big deal and for people to go braindead after an hour and a half, which happens more rarely than it does on bay's 3 hour rounds
