Abling Disability (#4485)

This PR implements a system for manipulating a client's color safely and also ports a prioritization system for sorting client color from /tg/. Currently this PR also implements client coloration in the form of color blindness, namely:
Monochromacy
Deuteranopia
Tritanopia
Protanopia

DTP are mild brain traumas, whereas monocrhomacy is a severe brain trauma.
Furthermore, this PR removes the Needs Glasses prompt in character creation, and replaces it with a disability selector, allowing people to more closely refine their special little snowflakes.
Current disabilities available:
Nervousness
Nearsightedness
Deuteranopia
Tritanopia
Protanopia
Deafness
Muteness
