Dark Mode Support

[Basketballforce]

Hey there Dolphin team!

I figured it was time that the Dolphin site had a dark/light mode toggle so I took a stab at it.

These changes include:

• Dark mode css
• Dark/Light toggle that uses browser/os preferences, local storage and icon toggling to change
• Curated edits for a pleasant dark mode experience
• Made up of 1 main css file, small edits to the main css styling, and js logic to handle icon switching
• Css for every (known) page on the dolphin-emu domain

Notes:

• Per the contributing instructions, the static and media file paths appear to be overwritten in Django. I'm not sure if this will occur but, I imagine it is possible that the added css and js href/script tag sources may be off in other people's environment. If so, let me know and I will take a look at fixing and providing screen shots so people can get an idea of what was changed

• I am able to test css edits on dolphin pages hosted publicly (using chrome dev tools) but, was unable to test some locally due to database limitations/Django db connections that appear to be outside my control.

Thank you!

Uploading some screenshots for reference. A local version with just the plain html, css, and js can be found here

Why orange?

[Basketballforce]

Its the color invert (inverted color) of the Dolphin blue logo.

I think it gives the dark mode its own unique flare but, changing this back to the classic blue would be very easy and do-able if preferred!

[MayImilae]

Definitely would be preferred. We use blue everywhere already, plus... bright orange on black is rather piercing imo.

I went and reverted the color changes from orange to the original blue. I have attached some screenshots for reference. I haven't updated the pull request since the original blue in dark mode doesn't have the best color contrast and dark mode experience (imo).

I will try to select a more "dark friendly" blue color scheme/theme that aligns to the original design. After which I will add more screenshots for reference and update the pull requests

After second review, the original blue looked perfectly fine for dark mode. Smaller additional edits have been made for quality of life. These are:

1. Links on the darker background/black background have been made a lighter shade of blue for color contrast sake.
2. Spacing between the light/dark mode icons and the hamburger toggle for mobile view has been increased for clearer/consistent separation of elements.
3. Button styling for the downloads page (btn-info) has been reverted back to original

The code has been updated/pushed to the pull request. Dark mode looks very similar to the most recent changes above in which dark mode was reverted to blue. I will add one or two screenshots below to reflect the new changes.

This looks great, and I'm picky with dark mode :P

For comparison, here's Dark Reader's automatic dark mode:

The native dark mode is almost always better than that too.
