Import VUDU rental history into a CSV format readable by Letterboxd.

generate_letterboxd_csv_from_vudu.js

// Run this in the browser bar: var el = document.createElement("script"); el.src=URL; document.body.appendChild(el);
//
// 1. Login to http://my.vudu.com
// 2. Open the Inspector (cmd-ctrl-I on OSX), and un this script (if popups are blocked, temporarily unblock popups from Vudu in your browser)
// 3. Grab the downloaded CSV file (probably with a random name), and load at http://letterboxd.com/import
// 
// How it works: this script is inserted into the Vudu page via a bookmarklet, grabs your session key, and 
// makes a call to Vudu's api. Then it parses the response and creates a CSV, which it then opens in a page as a data-uri.
