[Feature request] Dark Mode

Hello, I was wondering if it would be possible to add a dark mode option.  On most sites, I would normally just invert the colors on my display.  I think a dark mode would be better for this site, since when I invert the colors, the wood-patterned background becomes a bright, light blue.

Thanks for the suggestion, it's not something I had thought of doing, but I'll add it to my list of things to do.  Though it will probably be a while ... there are a lot of changes that are planned for the site that will come first.
