Scanner & Parser Changes (#735)

* Fixed a bug where partial volume support got missed on the epub parser.

* When a drive is unavailable during when a scan starts, abort so user doesn't loose half library if their networked drive goes down.

* Moved format for card details to highest level (since all chapters/files have same format) and added date added to each file to help when new chapters/files are added and grouped into a volume.

* Implemented handling on the UI when a series is deleted

* Added case for series removal for series detail

* Only redirect for this series
