Add new feature, set file date to episode aired date. Fix, use alternative Trakt API field for episode air time. Improve the Preview Rename tip.

Add, new setting "Set File Date to Airdate" on the Media Management tab of the Settings page to toggle this feature for new, imported and auto updating media files.

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 given that Windows undesirably adds time to file times set when using UTC.

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