wrong album-cover displayed

The faulty code is in elisa.plugins.poblesec.music_library:AlbumsViewMode : we currently don't retrieve the artist's name. There is no artist directly associated to an album, because there can be multiple artists associated to the different tracks of an album (eg on a soundtrack), but what we could do is retrieve the artist of the first track of the album and use it for the query to Amazon, that should give us much better matches already.

There is already a FIXME in the code at the place where retrieving the artist should be done.

The Right Way(TM) here seems to be to use the 'AlbumArtist' tag, which should also be used for grouping albums inside the Library > Albums view. The AlbumArtist should then be directly associated with an album, to avoid albums like 'The Best of' being displayed as one.

If the AlbumArtist tag is empty, the TrackArtist tag (if consistent in an album) should be used.

This kind of behavior seems to be consistent among several players (i.e. iTunes, Banshee and Rhythmbox too, I think).
