Implement Dark Github Chrome plugin's theme palette as an option

The new dark mode’s tones really nice, however the blueish tones make quite hard to see anything on GitHub.

There’s an unnofficial plugin I’ve been using for quite some time, and I know a lot more people out there also used it before dark mode being a thing here, it uses the classic “darcula” theme palette, and makes GitHub look a lot more eye-friendly without making contrast suffer.

Here are two images for anyone who wish to compare both themes.
