This reverts commit dcd32654ef5bba85df26dddf341928e990cd44d1.
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).

Also 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.

Spelling fix in icons/mob/suit.dmi
Changes Head of Security hat to lower case.
Removes useless jumpsuit hiding flags from security jackets.
Merge pull request #1652 from Perakp/securityClothing
