Added EpisodesWithFiles to get episodes in a serires that have an episode file
Fixed broken test
Add new feature, set file date to episode aired date. Fix, use alternative Trakt API field for episode air time. Build up the  Preview Rename help.

Fix, the Trakt API response show.air_time_utc contains erroneous data, this is replaced with show.air_time.

Add, new setting "Set File Date to Airdate" on the Media Management tab of the Settings page to toggle this feature for new/imported shows.

Change, home page "Series Editor" - "Rename" button to "Update Files" and add "Set File Date To Air Date" action button to this modal to add capability of updating legacy media.

Add non UTC functions as Windows currently adds an hour to file dates set when using UTC, monitor this change at next DST transition.
