Do not base64-encode non-binary files (containing only whitespace and
printable ASCII characters, which matches sane SVG files).

For SVG files the percent-encoded URIs are actually slightly longer
than the base64-encoded ones (~10%), but compress a lot better
resulting on 15-20% less data to transfer after gzip compression.

(The effect is best seen on the 'oojs-ui' module, which consists
mostly of SVG icons – especially after commenting out everything other
than 'oojs-ui.svg.css'.)

I tried this for binary files too, just in case; but as expected, they
suffer from a noticeable size increase even with compression (~15%).
