ComicInfo Refactor (#636)

Browse source 
* 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
