Security clothing crate

Adds the blue versions of fashionable security outfits and a crate you can order from cargo that contains 2x officer, 1x warden and 1x HoS outfits. Crate cost 30 supply points is more than standard costume (10 points) and wizard costume crates (20 points) and cheaper than loyalty implant crate (40 points).

Moves around security clothing items. For example HoS clothing was all in clothing/under/jobs/security, now every piece is in their respective category (under, suits, head). This doesn't change item paths.

Note this only adds the blue suits, not tan or dark blue versions. Doesn't add the boots since jackboots are good enough.
Sprites are the same as in softcurity project code/WorkInProgress/Sigyn/Softcurity/clothing
