A feed's own artwork has to be there before it is used (#89)

Browse Source 
A feed's itunes:image or <image><url> was stored without being asked
for, so a dead one stood in the way of the site's icon. Ken and Robin
Talk About Stuff names http://kenandrobin.wpengine.com/.../kartas_podcast.png,
a 404, while its site's apple-touch-icon works. The feed's artwork now has
to answer as an image, as the site icon already did, when the feed is
read in full; otherwise the site's icon is looked for.
