* Fixed an issue where when falling back to folder parsing, sometimes the folder name wouldn't parse well, like "Foo 50" which parses as "Foo". Now the fallback will check if we have a solid series parsed from filename before we attempt to parse a folder.
* Ensure SortName is set during a scan loop even if locked and it's empty string.
* Added some null checks for metadata update
* Fixed a bug where Updating a series name with a name of an existing series wouldn't properly check for existing series.
* Tweaked the logic of OnDeck to consider LastChapterCreated from all chapters in a series, not just those with progress.
* Fixed a bug where the hamburger menu was still visible on login/registration page despite not functioning
* Tweaked the logic of OnDeck to consider LastChapterCreated from all chapters in a series, not just those with progress.
* Removed 2 unused packages from ui
* Fixed some bugs around determining what the current installed version is in Announcements
* Use AnyAsync for a query to improve performance
* Fixed up some fallback code
* Tests are finally fixed
* Refactored all files to have Interfaces within the same file. Started moving over to file-scoped namespaces.
* Refactored common methods for getting underlying file's cover, pages, and extracting into 1 interface.
* More refactoring around removing dependence on explicit filetype testing for getting information.
* Code is buildable, tests are broken. Huge refactor (not completed) which makes most of DirectoryService testable with a mock filesystem (and thus the services that utilize it).
* Finished porting DirectoryService to use mocked filesystem implementation.
* Added a null check
* Added a null check
* Finished all unit tests for DirectoryService.
* Some misc cleanup on the code
* Fixed up some bugs from refactoring scan loop.
* Implemented CleanupService testing and refactored more of DirectoryService to be non-static.
Fixed a bug where cover file cleanup wasn't properly finding files due to a regex bug.
* Fixed an issue in CleanupBackup() where we weren't properly selecting database files older than 30 days. Finished CleanupService Tests.
* Refactored Flatten and RemoveNonImages to directory service to allow CacheService to be testable.
* Finally have CacheService tested. Rewrote GetCachedPagePath() to be much more straightforward & performant.
* Updated DefaultParserTests.cs to contain all existing tests and follow new test layout format.
* All tests fixed up
