optimize local library scanning (#112)

* add explicit warning for zero/invalid duration media items

* set dateadded on plex media versions

* add media stream table

* save local media streams to db

* save plex media streams to db

* add preferred language settings (no validation)

* use preferred language if possible

* code cleanup

* proper language code validation

* force scan of all libraries to pull in media streams
