* 🏭 Refactor outfit skillchips
- Skillchips now are on /datum/outfit, rather than /datum/outfit/job,
since we may want other roles to start with skillchips in the future.
- Skillchips are now a list of types to install, rather than a single
one.
- Traits for the deathsquad are now listed just below the deathsquad
initial antag datum definition.
* Remove accidental debug testing code
It was not intended for janitors to start with engineering skillchips,
and a really weak lightbulb removing skillchip.
* Fix indentation of comment
