this is admittedly not a usual use of stealth mode but it's nice to not
pop on/off the list when deadminned
(this is nice for event rounds since you're supposed to deadmin if in a
conflict role)
- moves stuff to more sane places so modules folder isn't so messy
- adds a world system that is the start of being able to data-define
world locations and having the game act differently based on which
location a map is in
there's no ability to separate 'pre-load map' (and a way for persistence
to inject this so we can have moving maps yet) but we can add it in
later since things are decently abstracted.
