Do not auto-download enclosures that are not audio or video

Blog feeds put each article's header image in an <enclosure>, so a text
feed read as a podcast full of episodes: 149 images, 74 MB across 11
feeds. media_types defaults to audio and video, with a per-feed override.

Such enclosures stay listed and stay downloadable by hand; the row names
what it is rather than saying "skipped". An unknown type is allowed, since
the real type is only known after downloading, and a torrent is allowed as
a container judged once unpacked.
