Shuttle datum code cleanup

[SECBATON-GRIFFON]

[administration][bugfix]

What this does

makes this not rely on so many global vars init ing it from the start, makes it more vareditable
makes shuttle datums only get created if they have an associated control computer or docking port, to save on unnecessary ones being created in what was once said global vars
stops the admin log reporting errors for shuttles that shouldn't even be in the round like the bagel ferry on box, or vaults that haven't loaded in

How it was tested

obsing as ghost, sending mining shuttle back and forth, checking world log, calling vox raider midround ruleset and sending shuttle back and forth, spawning the broke ufo vault and activating the shuttle control console, calling blob ruleset and causing a shuttle lockdown, then destroying the blob to lift it

Changelog

🆑

• bugfix: Shuttle datums now only get created if their docking ports or control computers actually exist, eliminating errors where non-existent shuttles complain about a lack of docking port in world logging.
• bugfix; Security outpost shuttles now get consistently locked down when necessary along with mining and research ones.
