Created a script to download project list as JSON

Turns out there's a simple way to download the data (that's used by the
melange site itself) - you just have to keep downloading data from
http://www.google-melange.com/gsoc/org/list/public/google/gsoc2014?fmt=json&limit=100&start={GIANT STRING HERE}

Until the "next" property in the json is "done".
