Remove From On Deck (#2131)

* Allow admins to customize the amount of progress time or last item added time for on deck calculation

* Implemented the ability to remove series from on deck. They will be removed until the user reads a new chapter.

Quite a few db lookup reduction calls for reading based stuff, like continue point, bookmarks, etc.
