Save books out of Safari Books Online

From http://objectivesea.tumblr.com/post/9033067018/safaribooks

This is hard. I spent way too much time figuring this out, because I was annoyed that a book I bought (Addison-Wesley) was available online for free, except only for 45 days after which payment was required. So I made this hack... probably useful to no one else, but here it is.

Requirements:

1. iPad.
2. Safari To Go (the Safari Books Online iPad app).
