The build system added support minifying gitweb.js through a
JavaScript minifier, but most minifiers come with support to
minify CSS files as well, so we should use it if we can.
This patch will add the same facilities to gitweb.css that
gitweb.js has for minification. That does not mean that they
will use the same minifier though, as it is not safe to assume
that all JavaScript minifiers will also minify CSS files.
Though the bandwidth savings will not be as dramatic as with
the JavaScript minifier, every byte saved is important.
