Bugfixes! (#157)

* More cases for parsing regex

* Fixed a bug where chapter cover images weren't being updated due to a missed not.

* Removed a piece of code that was needed for upgrading, since all beta users agreed to wipe db.

* Fixed InProgress to properly respect order and show more recent activity first. Issue is with IEntityDate LastModified not updating in DataContext.

* Updated dependencies to lastest stable.

* LastModified on Volumes wasn't updating, validated it does update when data is changed.

* Fixed #152 - Sorting issue when finding cover image.

* Fixed #151 - Sort files during scan.

* Fixed #161 - Remove files that don't exist from chapters during scan.

* Fixed #155 - Ignore images that start with !, expand cover detection by checking for the word cover as well as folder, and some code cleanup to make code more concise.

* Fixed #153 - Ensure that we persist series name changes and don't override on scanning.

* Fixed a broken unit test
