UA Civilian Overhaul

[AmoryBlaine]

Removes PvP survivor presets and a lot of background code they touch, along with a lot of corpses that clog up the presets and are built off of legacy presets. This is done in favour of more generic colonist presets in order to provide an aesthetically coherent roster of props to the setting, largely building off the props I added in the UPP update.

• Adds shirtless variants of all businesswear
• Adds khaki and grey businesswear
• Adds code around assignment name allowing variance for the same prop
• Drops security belt storage capacity
• Adds Hybrisa-styled vest
