Additional Memory Pressure Enhancements (#590)

* Added volume migrations. Added parser case for "Chapter 63 - The Promise Made for 520 Cenz.cbr"

* Added some info statements for when full library scans occur. For image apis, return the name of the file to aid in caching.

* When managing users, show the current logged in user at the top of the list. Added a message when no libraries have been setup but you are trying to add a user to a library.

* Removed an extra stream operation from SharpCompress cover image work. Removed an extra ToArray() from Book Reader for extracting PDF pages.

* Removed the left over comment

* Added parsing case for "Batman Beyond 04 (of 6) (1999)"

* Removed dead code
