FIX: change dark highlight for a11y

Fix #649

I spent some time on different forums and issues about color blindness (I am a geographer so it's also important to me when I'm producing maps) It seems that native is not the best choice effectively. Note that none of the existing Pygment highlighters are fully compatible with any vision deficiency.

Thus I installed the colorblindly extension for chrome and started playing with Pygments. It seems to me that the molokai is giving us the best results for Protanopia (read-blind) and Deuteranopia (green-blind) which are the most comons form of color blindness.

Here are demo in both Python an JSON:

	normal	green-b	red-b

Let me know what you think

Works for me, especially if it improves a11y - also dracula is a cooler name

also dracula is a cooler name

Note that the final choice is unfortunately less cool, it's "monokai"
