* Added ReadingList age rating from all series and started on some unit tests for the new flows.
* Wrote more unit tests for Reading Lists
* Added ability to restrict user accounts to a given age rating via admin edit user modal and invite user. This commit contains all basic code, but no query modifications.
* When updating a reading list's title via UI, explicitly check if there is an existing RL with the same title.
* Refactored Reading List calculation to work properly in the flows it's invoked from.
* Cleaned up an unused method
* Promoted Collections no longer show tags where a Series exists within them that is above the user's age rating.
* Collection search now respects age restrictions
* Series Detail page now checks if the user has explicit access (as a user might bypass with direct url access)
* Hooked up age restriction for dashboard activity streams.
* Refactored some methods from Series Controller and Library Controller to a new Search Controller to keep things organized
* Updated Search to respect age restrictions
* Refactored all the Age Restriction queries to extensions
* Related Series no longer show up if they are out of the age restriction
* Fixed a bad mapping for the update age restriction api
* Fixed a UI state change after updating age restriction
* Fixed unit test
* Added a migration for reading lists
* Code cleanup
* Refactored invite user flow to separate error handling on create user flow and email flow. This should help users that have unique situations.
* Switch to using files to check LastWriteTime. Debug code in for Robbie to test on rclone
* Updated Parser namespace. Changed the LastWriteTime to check all files and folders.
* Tweaked a Migration to log correctly only if something is going to be done.
* Refactored Reading List Controller code into a dedicated service and cleaned up some methods that aren't needed anymore.
* Fixed a bug where adding a new item to a reading list wasn't adding it at the end.
* Fixed an issue where collection page would re-render the same covers on multiple items.
* Fixed a missing margin-top which made the page extras drawer not render correctly and hence unclosable on small screens.
* Added some timeout on manage users screen to give data time to flush.
Added a dedicated token log for account flows, in case url encoding plays a part (but from testing it doesn't).
* Reverted back to building for ES6 instead of es2020 for old Safari 12.5.5 browsers (10MB difference in build size).
* Cleaned up the logic in removing series not found during scan loop.
* Tweaked the timings for Library Watcher to 1 min and reprocess queue every 30 seconds.
