Release Shakeout (#655)

* Cleaned up some code. Fixed an issue on books with good table of contents not allowing line tracking (progress) from being saved. Changed Save to Defaults on light mode to be primary.

* Fixed a bug where deleting reading items would not actually delete them

* Fixed a bug where after ordering reading lists then deleting the order would be undone (develop)

* Code cleanup
