Humble bundle book bundles - download all books at once

hb_all_books_dl.js

/* 
After purchasing a humble book bundle, go to your download page for that bundle. 
Open a console window for the page and paste in the below javascript

this fork downloads all formats and does so without using jquery (since that didnt work for me)

note that if you are in chrome, chrome will not download the pdfs for you by default, to fix this
type “about:plugins” in the address bar and disable chrome's pdf viewer

    if (a && a.text && pattern.test(a.text.trim())) {
        // changed to href - now works with current FF/Chrome
        download(a.attributes['href'].value, i);
