Rename Colourblindness

[Sancronis]

So the colourblindness ingame is an extremely rare type called monochromatic colourblindess, so I'd suggest renaming it to monochromatic colourblindness to reflect this.

Unless we're aiming to implement a variety of types of colourblindess, I don't see a need for the differentiation.

 

In layman's terms, colourblindness is the inability to see colour. As we've only the one option, we don't really require such specificity.
