New locales and zopfli
I've been working on localizing app website, and noticed that a few popular country-variants were missing from the list of generated badges. So this adds them.
Then this also zopfli-compresses all the PNGs to make them about 25% smaller, and makes smaller files than pngcrush. Zopfli is available using apt-get install zopfli
