Shakeout Part 2 (#630)

* When flattening directories, ensure the order or directories being enumerated follows a natural sort. Some users are discovering directories in a different order than other machines.

* Added a case for volume parsing and fixed a poorly designed negative lookahead.

Added a sentence case pipe for formatting things.

Added time for all dates.

* Some more sentence case

* Register user now has a white input

* Fixed an issue with Manga up/down reading mode where top of the page was going forwards, when it should have gone backwards

* Reworked some code to ensure that scanseries doesn't show errors where in fact there was just nothing to update.

* Last updated should be working as intended for new library flow.

* Code smell
