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.

On mobile, when book conversion is enabled and using the cabliBlur theme, the upload menu appears behind the description text area making it difficult (though not impossible with some careful guesswork around where the buttons should be).
This commit fixes the styling of this section so that it no longer appears behind the description text area.
This commit allows the web reader to read the KEPUB (Kobo EPUB) files,
and also shows the file sizes. This is especially useful if you have
giant EPUB files with built-in audiobooks and media overlays.
