remove links for internal links
fix a link
convert to SASS
move comments to above the lines to which they refer
remove css file; now in minimal.scss
add sass cache
add support for SASS
change license

    I probably can't license the SASS under cc0 because ethan
    schoonover's solarized is MIT licensed; I just made this BSD
    2-clause to be sure, and included the MIT license too.
