"Album" Art - beyond albums

[mdp]

I once suggested that it would be nice to let minim server look for pictures to put in the artist list, like twonky and asset does.

First it should look in the artist folder; if there is one jpg included in the tree beside the album folders, this should be used as art for the artist.
If not it could pick first jpg in first album folder or the best quality jpg or the newest.

Then you can choose your self to whether to put a jpg in the artist folder or let Minim pick one for you.
