Add button colors to UiStyle

[Monniasza]

This PR adds configurable button colors by UiStyle, with the variable ButtonColor

[Monniasza]

I forgot to add colors for checkboxes and radios too.

Hi, thanks so much for this PR!

Unfortunately, it looks like there are also a bunch of other, unrelated files/changes included. Please resolve these before I can merge this :)

Feel free to also add default color properties for radio buttons and checkboxes, as you suggested!

[Monniasza]

I've thought to add manually configurable colors to radio buttons. I'll add the full set of background colors too to every element.

Maybe you would just copy the .gitignore from me @ https://github.com/Monniasza/TranSimCS/blob/master/.gitignore

[Monniasza]

Requested changes done. Feel free to request more or accept them as they are.

[Ellpeck]

Hi, thanks for these changes! You still haven't untracked the .vs folder after adding it to the gitignore, so please do that :)

[Monniasza]

Untracked in d36c860

[Ellpeck]

Your gitignore is correct, and was correct the first time. You need to untrack the files that were already committed before using git.

[Ellpeck]

Some additional, small notes (only the first of which is really all that relevant!) Thanks :)

[Monniasza]

@Ellpeck Are you willing to merge this PR right now?

[Ellpeck]

Hi! You haven't done some of the things I requested yet. You still have the .vs folder tracked, and there's still changes to the UI demo that I don't think should be on main.

[Monniasza]

The Git implementation of the Visual Studio 2022 doesn't respect the .gitignore file. How could I fix it?

[Monniasza]

As an addition, should I make all untextured UI textures white and set different default colors instead of using colored textures? I've now removed colors from the demo as you have requested.

[Monniasza]

Fianlly deleted gitignored files, by using git rm -r --cached . and git add .. https://stackoverflow.com/a/67828150

[Ellpeck]

Hi! All the stuff I commented on now looks good, thanks :)

For some reason, you now added a second version of the submodules from the ThirdParty directory into the root folder though? Why did you do that?

[Ellpeck]

Thank you so much! :)

[Monniasza]

@Ellpeck When are you going to release a new version of this library, now with these enhancements?

[Ellpeck]

Releases are pretty infrequent, so I recommend using the prereleases :)
