New Schemes 

Made 5 new color schemes to be used with Base16 Builder. 

Levity blue, brown and gray are *high-saturation* schemes with Solarized-like symmetrical CIE-Lab lightness relations between the colors. The foreground colors are meant to be perfectly readable with both the light and dark backgrounds.  

The grayscale is a monochromatic scheme :)

Marrakesh has nice background colors for both the light and dark variations, and some exotic color combos, like "golden" yellow on dark brown.
