Scanner Performance Improvements (#1774)

Browse source 
* Refactored the Genre code to be faster and used a dictonary to avoid some lookups. May fix the rare foreign constraint issue.

* Refactored tag to the same implementation as Genre. Ensure when grabbing tags from ComicInfo, we normalize and throw out duplicates.

* Removed an internal "external" field that was planned for Genres and Tags, but now with new plugin architecture, not needed.
