* Lots of cleanup on the warnings in the solution. Deprecated IsLastWriteLessThan and made a new method HasFileBeenModifiedSince.
* Added some tests for the new extension method.
* Changed filter import to use correct import
* Scan Series now uses Refresh Metadata for Series, rather than library one.
* Fixed an issue where cover generation wasn't properly taking forced update into consideration. Removed a case of cover generation for no reason.
* Fixed series downloads not triggering backend call
* Removed some extra spam for the console
* Implemented the code to update RowVersion, which is our concurrency check
* Fixed a critical issue where more than one bookmark could occur for a given chapter due to a race condition. Now we use concurrency checks and we also gracefully allow more than one row, by only grabbing first.
* Cleaned up the logic for IHasConcurencyToken and updated the setters to be private.
* Lots of comments and when deleting a library, remove any user progress items for which chapters don't exist.
* When deleting a Series, cleanup user progress rows.
* Now after a scan of library, if a series is removed, collection tags are pruned as well if there are no longer any series bound to it.
* Updated the image on the Readme to show a better picture
* Small code cleanup to remove null check modifier as I check for null just before then
* Fixed images loading multiple times due to using function in binding with random. You can now click chapter images to read that chapter specifically.
* Fixed cards being different sizes when read vs unread
* Moved over Robbie's workflow changes from notifier. Commented out activity indicators as that is not shipping with this release.
* Remove code that isn't needed
* Reverted GA
* Changed GA to trigger only when HEAD is updated
* Added book reader reading direction preference
* Adds a new marker to the AppUserProgress to capture nearest anchor for resuming scroll point when reading books. Refactored bookmark api to return a BookmarkDto which includes this new data.
