Adds verb to change eye color at will (if mechanical)

Browse Source 
Adds a verb used by humanoid mobs that have mechanical eyes, which allows them to pick a new color, and have it applied instantly.
Adds some helper functions, specifically hex2rgb(), to convert hexadecimal colors to a list of numbers for r, g, and b.
