Minor additons to Synth vendor, renames a uniform used by colonists

[QuickLode]

About the pull request

This PR adds 2 items to Synth Vendor, a purple armband and a requested white suit & tie.

This suit & tie was previously named "Captain's Service Uniform" and used for years as a colonist uniform - specifically the plain clothes WY Security Guard. The name is weird.

However, at some point, it was renamed to Commanding Officer's Service Uniform and this makes the name even worse. Plain clothed WYSec are the guys in suits next to CLs who don't break the mood with their ugly orange or white more police/militarized counterparts. To be honest i have attended a lot of CO events and I've never seen anyone wear this LOL
It is a suit and tie with black slacks, so I understand why it was added originally. The distinction of it being a dress down uniform is unnecessary

I added a counterpart so we don't have to have this distinction while keeping the classic colonists in.

Explain why it's good for the game

This separates the colony/synths from COs so that they don't have to share names, even if its rarely used by the latter. More immersive this way
