We had a bunch of different places where we had link colors of various

shades of blue. This standardizes them all into a single @link-color

definition, which is the same as @blue-20. While doing this, I decided

that the definition for that particular color (drawn from a mockup we

have) wasn't really blue enough to provide real contrast against white

and grey backgrounds, so I pushed the saturation a little bit.

Flipped through the UI and looked for all the links I could find.
