Expanded Metadata for EPUBs (#1965)

* Fixed a bug breaking ability to save server settings

* Explicitly capture more people roles from Epubs, else fallback to how we do it now. It seems to be getting called twice and 2nd time is overriding data. Not sure why

* Refactored the code to clean it up

* Added support for generating collections or reading list based on dc:title and collection title-type with an optional display-seq.

* ReadingList/Collection support can't be done until VersOne supports. https://github.com/vers-one/EpubReader/issues/81

* Double include author for epub parsing and let the People code handle removing duplicates.
