Enforced config background colours have serious accessibility issues for some types of colour blindness

Added screenshots showing the simulated colour blindness types.

Added Neurocracy/Omnipedia link and info.

Rewrote Neurocracy info to be more descriptive of how it's similar but also different from Config Enforce.

Added Omnipedia screenshots.

Added alt text for all the screenshots.
