// How to use this:
// 1. Go to the desired profile page on coderwall, like http://coderwall.com/marcinbunsch
// 2. Paste this gist in the JS console 
//
// You can also probably use this in greasemonkey and dot.js
//
// Also, it was tested in Chrome, Firefox and Safari, it probably will 
// not work in IE, but I just don't care about it ;)
//
// UPDATE: Coderwall made changes to the site and I cannot retrieve the achievements, so they are hardcoded, taken from a cached version of the achievements page
