Adds a direct download button for EPUB format to each work blurb on AO3's works index pages.
The code is from tuff, who wrote the original "AO3 download buttons" script, except modified to only add an ePub download button called "save" to all work pages.
- Useful for quickly downloading fics on your "Marked Later" list, Bookmarks list, etc. to your local storage
- Can easily modify in source editor to automatically pull pdf/mobi/html, by replacing "epub" with file type of your choice
- Replace "save" with text/icon of your choice
