More date options

[Cronvs]

Changes year in movies to a date, adds a series_date for when the matched series first aired, and add the capability to use the datetime attributes for formatting like so: {date.year}, {date.month}, or {series_date.year}. This would make formatting series conform to for example jellyfin show naming more.

Was confused as to why supplying an id would diminish search hits, I made it so that date search for tvdb now check if month and day are default values, and if so, then check that season and episode are the same to get matches, and only compare the year of either episode or series, not precise dates of episodes.
Also, I got annoyed with double year tagging. TVDB solves duplicates of names by suffixing the year, I added format logic to remove any year tagging from series if the format spec already provides date tagging.
