Book Feedback and small bugs (#183)

* Remove automatic retry for scanLibraries as if something fails, it wont pass magically. Catch exceptions when opening books for parsing and swallow to ignore the file.

* Delete extra attempts

* Switched to using FirstOrDefault for finding existing series. This will help avoid pointless crashes.

* Updated message when duplicate series are found (not sure how this happens)

* Fixed a negation for deleting volumes where files still exist.

* Implemented the ability to automatically scale the manga reader based on screen size.
