New PDF Reader (#1324)

Browse source 
* Refactored all the code that opens the reader to use a unified function. Added new library and setup basic pdf reader route.

* Progress saving is implemented. Targeting ES6 now.

* Customized the toolbar to remove things we don't want, made the download button download with correct filename. Adjusted zoom setting to work well on first load regardless of device.

* Stream the pdf file to the UI rather than handling the download ourselves.

* Started implementing a custom toolbar.

* Fixed up the jump bar calculations

* Fixed filtering being broken

* Pushing up for Robbie to cleanup the toolbar layout

* Added an additional button. Working on logic while robbie takes styling

* Tried to fix the code for robbie

* Tweaks for fonts

* Added button for book mode, but doesn't seem to work after renderer is built

* Removed book mode

* Removed the old image caching code for pdfs as it's not needed with new reader

* Removed the interfaces to extract images from pdf.

* Fixed original pagination area not scaling correctly

* Integrated series remove events to library detail

* Cleaned up the getter naming convention

* Cleaned up some of the manga reader code to reduce cluter and improve re-use

* Implemented Japanese parser support for volume and chapters.

* Fixed a bug where resetting scroll in manga reader wasn't working

* Fixed a bug where word count grew on each scan.

* Removed unused variable

* Ensure we calculate word count on files with their own cache timestamp

* Adjusted size of reel headers

* Put some code in for moving on original image with keyboard, but it's not in use.

* Cleaned up the css for the pdf reader

* Cleaned up the code

* Tweaked the list item so we show scrollbar now when fully read
