Library Recomendations (#1236)

* Updated cover regex for finding cover images in archives to ignore back_cover or back-cover

* Fixed an issue where Tags wouldn't save due to not pulling them from the DB.

* Refactored All series to it's own lazy loaded module

* Modularized Dashboard and library detail. Had to change main dashboard page to be libraries. Subject to change.

* Refactored login component into registration module

* Series Detail module created

* Refactored nav stuff into it's own module, not lazy loaded, but self contained.

* Refactored theme component into a dev only module so we don't incur load for temp testing modules

* Finished off modularization code. Only missing thing is to re-introduce some dashboard functionality for library view.

* Implemented a basic recommendation page for library detail
