* Fixed an issue where "blank" images could occur at the end of a webtoon if the users scrolls up and down when near the last page, due to a gap in checking if prefetch range is within totalPages bound.
* Fixed goto first/last page not triggering webtoon reader to move. Disabled reading direction when in webtoon reader.
* Added some DOM Purging, images that are +/- bufferPages (5) from you will no longer reside in DOM. This helps on low end phones.
