Add tags and series to updates
Currently only songs are updated, but if a tag or series (aliases, i18n, etc) has been modified, its contents will never be redownloaded unless a song using them is being updated.
to do:
-
Add modified_at field to series and tag files -
Make sure KM Server exposes these fields and has a /raw API endpoint for them. -
Add the whole check to KM App's UpdateBase function (after all songs have been downloaded so this doesn't trigger needless downloads)
