Nord Dark Theme

From the legendary @Crozbo, who already gave us the fantastic Nord Dark Theme Extension, which has had raving reviews from hundreds of happy users (well, many), comes... ta-da! The Theme! Much more lightweight than the actual extension, but perfectly executed within the guidelines of the Nord Theme (nordtheme [dot] com). Because the Nord Theme is not just a palette of fancy colours. That's the easy part. It's also a set of graphical guidelines on how to use each colour in the appropriate way. That's how you get a smooth transition from well-designed theme templates (such as those in Joplin or Typora or VSCode...), and everything looks and feels exactly the same. As a fellow template designer (for the Nova editor, which only Mac coders are familiar with), I salute you, and thank you profusely for your hard work! It stands out from the rest, and it comes as close as possible to what could be considered the "official" Nord Theme with the Arctic Ice Studio's stamp of approval! Well done!
