Comment 3 for bug 1559363

I have fixed this partially for v0.8. I have added the setting to refresh podcast artwork which will *only* work for podcasts that you added via the search feature. Podcasts added by Url don't work. The reasoning is simple, the podcast feeds added via url don't follow a standard format and as such Podbird's parser is finding trouble fetching the new cover art. This is the best I could get done in the time we have.
