This commit adds the Nightshift lighting mode from /tg/. From 19:00 to
07:00 in station time, the station will go into a reduced-lighting mode,
with dimmed lights across the station.
In conjunction with this, there is a new configuration option to start
the shift time at a random time other than 12:00, so that players are
more likely to experience a night shift (as opposed to having to have a
7 hour round).
Air Traffic Control from Polaris. Every TBD to TBD minutes, a radio
exchange happens between a ship and Cyberiad Space Control, ranging from
system transfer permission to declaring an emergency.
Refactored MAP_NAME into /datum/map files. This also allows for built-in
map lore (really just the name and system, which is only used for ATC).
Secondary commit will adjust all of the lore to match our own instead of
Polaris's.
