Misc Bugfixes (#1378)

* Fixed an issue where sometimes when loading the next page, the pagination area wouldn't be properly setup due to a missed rendering cycle

* Refactored BookController to thin it out and refactor some of the functions to apply IOC. Added some split query statements on a few queries.

* Added Split Query to many queries

* Added a visual indicator for loading state of PDF. Will spruce up css later.

* Added back in logic

* Fixed flash of white when refreshing browser

* Hooked in a loading progress bar for the pdf reader

* Close the pdf reader when pressing ESC
