Preparation for Release (#2135)

* Don't allow Comic libraries to do any scrobbling as there aren't any Comic scrobbling providers yet.

* Fixed a bug where if you have multiple libraries pointing the same folder (for whatever reason), the Scan Folder api could be rejected.

* Handle if publication from an epub is empty to avoid a bad parse error

* Cleaned up some hardcoded default strings.

* Fixed up some defaulting code for the cache size.

* Changed how moving something back to on deck works after it's been removed. Now any progress will trigger it, as epubs don't have chapters.

* Ignore .caltrash, which is a Calibre managed folder, when scanning.

* Added the ability to see Volume Last Read Date (or individual chapter) in details drawer. Hover over the clock for the full timestamp.
