Air Traffic Control & Map Lore

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.
