Feature request: Podcast category

In-app we try to detect podcast.

It would be nice to propose it as a separate category, so a medialibrary meta would allow querying podcasts.

For now, on Android, we detect podcasts with this:

• Genre is (case insensitive): "podcast" or "audiobooks" or "audiobook" or "speech" or "vocal"
• media is not tagged and length is > 15 minutes.

Maybe 15 minutes is too much, and we may sort audiobooks out of podcast category.
