In-Depth Filtering (#850)

* Laying the foundation for the filter rework

* Filtering by Genre is now possible.

* Cleaned up code and preparing for People filtering

* People filtering is hooked up for the frontend

* Filtering now works. On Deck does not work with filtering currently due to a unique implementation.

* More cleanup

* Implemented the ability to reset the filters

* Added a mobile drawer for filtering

* Added some additional cases for NaturalSortComparer. Filter now uses a drawer on smaller screens.

* Fixed a bug where backup service was not pointing to the correct directory.

* Undid the fix, it's working as expected
