Optionally depend on sassc to generate the theme CSS

Browse Source 
Instead of using Ruby/Sass to generate the CSS from SCSS files, we can
use the faster and more lightweight libsass/sassc binary.

We can keep the CSS files in Git to make it easier to dist GTK+, but we
can add rules to ensure they get rebuilt if the source SCSS changes.
