Title: Add mix, shade & tint functions

Use these in color schemes for some automatic bright & dark versions. They will
even stay in-theme, since the functions will use the theme's defined darkest and
brightest colors.

Shout out to the [Sass](http://sass-lang.com/) & [Bourbon](http://bourbon.io)
projects for the code!
