Jump Bar Testing (#1302)

Browse source 
* Implemented a basic jump bar for the library view. This currently just interacts with existing pagination controls and is not inlined with infinite scroll yet. This is a first pass implementation.

* Refactored time estimates into the reading service.

* Cleaned up when the jump bar is shown to mimic pagination controls

* Cleanup up code in reader service.

* Scroll to card when selecting a jump key that is shown on the current page.

* Ensure estimated times always has the smaller number on left hand side.

* Fixed a bug with a missing vertical rule

* Fixed an off by 1 pixel for search overlay
