The media-type filter stopped new image enclosures being fetched, but ones
already on disk still got a play button and an <audio> element, because
the UI tested for a path rather than for a playable type. Four places did
this, including play() itself, which picked the first downloaded enclosure
whatever it was.
isPlayable() checks audio/* or video/*, falling back to the extension when
a feed declares no type. A downloaded non-media file now shows as its kind
with Save and Delete, so it stays available without posing as an episode.
