Readme Fix

Fixed an issue with relative file paths causing the image in the readme file not to show properly inside Atom.

dark-snek-syntax

A syntax highlighting theme for MagicPython based off 'One Dark' with lots of tweaks to the existing colors and several Python-specific syntax highlighting features not taken advantage of in the original.

It blends in cleanly the 'One Dark' UI theme, but any dark ui theme should do.

Non-python languages will still retain the base syntax highlighting from the 'One Dark' syntax theme.
