Restricted Profiles (#1581)

* 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
