simple CSS parser and inliner in Go (library)

 Golang library with simple CSS parser and HTML inliner.
 See associated "douceur" binary for a basic command-line executable of this
 library.
 .
 Parser is vaguely inspired by CSS Syntax Module Level 3
 (https://www.w3.org/TR/css-syntax-3/) and corresponding JS parser
 (https://github.com/tabatkins/parse-css).
 .
 Inliner only parses CSS defined in HTML document; it DOES NOT fetch
 external stylesheets (for now). Inliner inserts additional attributes when
 possible.
 .
