Web font downloader/inliner.

Downloads a set of web fonts specified by @font-face rules in a CSS file. By default, woff2 equivalents are inlined as the modern browsers all support it.

By inlining woff files, this reduces the number of server roundtrips by two in the best case (the external CSS and woff files), one in the worst (just the external CSS). By reducing roundtrips we can reduce the amount of time we risk showing a flash of unstyled or hidden text content.

This tool is currently designed to work against Google's font server but should work against any hosted CSS font that uses @font-face.
