* Fixed some security issues in dev env
* When deleting folders in bookmark cleanup, delete empty folders correctly.
* When a new library is created and cards are added, cards can have a blank library name. Card library name code is reworked to be much lighter on memory.
* Added a config for github issues to disable blank issues.
* Skip any sort of directory iteration code if we haven't deleted any bookmarks.
* Fixed a bug where some style overrides were duplicating. Now logic is much more targetted, only applying to the correct tags.
* Applied sorting to the filtering apis.
* Reverted one of my changes for a better version Robbie did.
* 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
