Purpose of change

Much like with hiding clothing, hiding traits and mutations is a much-desired feature for various reasons. Considering how much it's desired and how simple it was to port, I see no reason not to bring it in.

Describe the solution

Ports CleverRaven/Cataclysm-DDA#52058 from DDA.

Describe alternatives you've considered

• Reinvent the wheel
• Implode
• Explode
• Wait for someone else to do it

Testing

It builds, it works (on my machine anyway)

Additional context

2/3 of the hiding visuals ports that RoyalFox threw at us done. Next up, Bionics! (For whoever ends up taking that one on)

Don't worry Chaos, this time I made sure the keybind was BN-ified the first time ;P

[autofix-ci]

Autofix has formatted code style violation in this PR.

I edit commits locally (e.g: git, github desktop) and want to keep autofix

1. Run git pull. this will merge the automated commit into your local copy of the PR branch.
2. Continue working.

I do not want the automated commit

1. Format your code locally, then commit it.
2. Run git push --force to force push your branch. This will overwrite the automated commit on remote with your local one.
3. Continue working.

If you don't do this, your following commits will be based on the old commit, and cause MERGE CONFLICT.

Needs a windows user for testing but this should be fine, it builds off the previous PR.

Compiled and tested, it works but has a spelling error.
