Multi-Page Viewer Plus

Description:
This user script provides a slideshow option for MPV (Multi-Page Viewer HATH perk required), as well as minor design improvements.
Code is pretty self-describing so you can edit it with no trouble. If you found a bug or added new neat feature to it, please post a message bellow so that I can improve this script.
