Goals:
- Accept a list of urls with optional custom titles, and a user config.
- Fetch each, including images.
- Process each for readability (format text, remove ads and clutter).
- Stitch them together into a single epub, with a cover page.
- Based on user config:
- Generate a hyperlinked table of contents.
- Generate page numbers.
- Print the date on the cover page.
- Email the epub file to the given email address, ideally one associated with an eReader.
