Pull request checklist:

Description

Adds a setting in the user highlights page to enable highlights for your own messages

Adds a highlight option in the users tab which highlights the current user's messages (automatic)

Closes #3814

[MrAuro]

Had someone test it and right now if you don't change the color then the highlight will be black instead of the default blue. Changing the color to anything else will work.

I'll fix this either tomorrow or sunday

I personally think this setting should not be enabled by default.

I agree that it should be disabled by default, and I also think it should be under the "Users" tab

Small feedback, can give it a more proper check during the weekend

I made some cosmetic changes, I'd like you to take a quick look at the code again and test things to ensure everything works as expected for you.

In addition, if you could update the PR with a new screenshot of what it looks like that would be nice

Feedback from others: How is this default color choice?
