Humble Bundle purchased game counter

gistfile1.js

/*
  Description: JS snippet to determine how many games you have in your humble bundle library
  for a given platform. it won't filter duplicates (it does happen, but its rare) and it 
  will only count the ones in the main list(s), which appear to only be the drm free ones, 
  so those purchased via bundles that only give you steam keys, such as the humble THQ 
  bundle or the humble jumbo bundle, wont be included in the count.

  Instructions: navigate to your main humble bundle library, select one of the platform 
  filters (eg. Windows, Mac OS X), open the browser console (in Chrome on mac the 
  shortcut is cmd-alt-j), and copy this snippit into the prompt and press 
  enter. the count will appear as the result. ENJOY!
