* Introduced a lock for DB work during the scan to hopefully reduce the concurrency issues
* Don't allow multiple theme scans to occur
* Fixed bulk actions not having all actions due to nested actionable menu changes
* Refactored the Scan loop to be synchronous to avoid any issues. After first loop, no real performance issues.
* Updated the LibraryWatcher when under many internal buffer full issues, to suspend watching for a full hour, to allow whatever downloading to complete.
* Removed Semaphore as it's not needed anymore
* Updated the output for logger to explicitly say from Kavita (if you're pushing to Seq)
* Fixed a broken test
* Fixed ReleaseYear not populating due to a change from a contributor around how to populate ReleaseYear.
* Ensure when scan folder runs, that we don't double enqueue the same tasks.
* Fixed user settings not loading the correct tab
* Changed the Release Year -> Release
* Added more refresh hooks in reader to hopefully ensure faster refreshes
* Reset images between chapter loads to help flush image faster. Don't show broken image icon when an image is still loading.
* Fixed the prefetcher not properly loading the correct images and hence, allowing a bit of lag between chapter loads.
* Code smells
