* Some small changes to how maxPage is handled for better page tracking on webtoon reader.

* Fixed a bug in cover image selection (#756)

* Refactored webtoon reader to report page progress exactly as manga reader does. In addition, manga reader moved progress saving to setPageNumber making them the same.
