## About The Pull Request
Cybersun (Kansatu), SUNS (Aegis) and NGR (Hyena) engineers/mechanics now
start with GEC jumpsuits, **if** you have the "alternate jumpsuit"
option selected in the loadout.

Also, this change does not apply to the Hardliners, as I'm not sure if
they would hire GEC engis. Correct me on that if I'm wrong.

## Why It's Good For The Game
It is said in lore that those factions tend to hire GEC workers, but
there wasn't really anything to back it up in game.
It's also a treat for all the GEC characters. The ability to show their
true colors on board of other faction's ships.

changelogs should generally represent how a player might be affected by
the changes rather than a summary of the PR's contents. -->
