Links many map-specific details such as the station name, z-level information, and allowed jobs from global vars to map datum vars, which should help us maintain multiple maps at once in the future, which will be needed for the future Southern Cross.
Note that a config change will be needed to change GENERATE_ASTEROID to GENERATE_MAP, otherwise no changes should be required to continue normal map usage.
To change to a different map, it's suggested to tick the file that ticks all the other needed files, which for the Northern Star is called northern_star.dm.
The short naming of central command has been really inconsistent across
the game's files. This has always annoyed the shit out of me.
CentComm and Centcomm and Centcom are now all CentCom, specifically with
that capitalization. Why one M instead of two M's? Because Comm with two
'M's = Communications. Hence, Telecomms, NOT Telecoms. Telecoms is
incorrect. CentCom was also chosen because CentCom with one M and this
casing is most found throughout the game's files.
Speaking of Telecomms, I corrected one instance in the game where it's
Telecom. Like I said, this is not correct. There was only one
inconsistency.
Likewise, Nanotrasen has been changed to NanoTrasen. Nanotrasen only
appears 20 times, where NanoTrasen appears 62. NanoTrasen is clearly the
preferred, correct naming.
Makes the name of the starsystem and station generic such that it can be modified in global.dm and replace the strings where it is used. This won't have an effect on Polaris itself, but makes changing the name much more simple for forks. Using string concat constants on the advice of Psi.
