* Implemented methods to parse out the whole ComicInfo file and a mock ComicInfo from epub files.
* Removed unused imports. ScanSeries needs to cleanup deleted chapters and call RefreshMetadata. Ensure after scan we cleanup tags without any series.
* Random cleanup
* Added some comments about data getting stale and not updating.
* Removed old Summary methods in favor of the ComicInfo versions
* Added a missing property
* Fixed unit test
* Refactored the performance of GetChapter/BookInfo API to have a 10x speed improvement and to use common code, rather than duplicating code. Removed an api param that is no longer needed.
* Book reader now has dedicated buttons to jump to next/prev chapter as well as through page buttons
