Southern Cross shuttles one and two can now launch.
Adds missing areas for shuttles 1 and 2.
Shuttles warming up, moving, or stopping now make a nice sound, ported from /tg/.
Rearranges shuttle datum/computer definitions to make it easier to read.
Removes cloaking abilities for most multi-shuttles.
Lowers transit time for multi-shuttles. Can be raised later if desired.
Shuttles now set themselves up upon being instantiated instead of relying on a monolithic proc in the shuttle controller.
Shuttles can now be defined more cleanly on a per-map basis, as well.
Accidentally fixes a broken admin shuttle.
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.
Computers now use an overlay based system, instead of demanding a full set of icons (on, off, broken) for every different computer.
Partially ports ParadiseSS13/Paradise#1468 which is a port of tgstation/-tg-station#9931.
Everything in game/machinery/computers/ and modules/shuttles should now have properly (de)capitalized names. Computer, board and research names should now be coherent, too. Adds a research for employment records circuit board.
Moves all ferry shuttle processing into one place: the new shuttle
controller.
Also cleans up the emergency shuttle controller a bit more and fixes
multi-shuttle cooldown.
