Loadouts / Traits / Character Requirements mega-issue

[DangerRevolution]

Description

As requested and spoken about:

Problems:

• [ ] test fail should be thrown if using an invalid ID inside a loadout entry
• [ ] Categories will overflow the UI if there's too many, or a user's screen is too small
• [ ] Selecting an item you fit the requirements for; then failing to meet the requirements should de-select the item (or something similar)
• [ ] Traits / Loadouts will reset scroll upon any update
• [ ] Traits / Loadouts you do not meet the requirements for; that you then switch to meet the requirements will not update the entry until Loadouts / traits is updated i.e if I'm an Oni, and I want a Felinid trait so I switch to Felinid; the trait menu won't update until I do something to update it

Problems (needs replicating or testing)

• [x] Whitelist doesn't work
• [ ] JobBans don't work
• [ ] AntagBans don't work (Wizden issue, there's a PR open to fix this but I doubt it'd work for us)
• [ ] Weight on the CharacterProfile and the Entity don't match up. (ask MnemoTechnician)

Requested Features
