The code in epub-progress.js was causing the epub file to be loaded twice over the network, because it created a second instance of the epub.js library. I moved all the progress percentage display code into epub.js. Only the locationchange polyfill code was left in the separate file, renamed to locationchange-polyfill.js. I rewrote the percentage progress code to use epub.js events, giving more succinct and readable code. Also, I added localStorage caching of the epub location calculations, required for displaying percentage progress, which can take up to 60-90 seconds to calculate on longer ebooks. This localStorage caching approach is recommended by epub.js in the `locations.html` example in their repo. Signed-off-by: Ross Williams <ross@ross-williams.net>
