album art not showed consistently

I am working on a change that should do what you want for [folder view] if you set indexArtwork=auto as described in this post.

With this change, if a folder doesn't have artwork and if indexArtwork=auto is enabled, all subfolders underneath the folder would be checked for artwork. If any of these subfolders has artwork, the first subfolder artwork image found would be shown for the folder.

For example, with this hierarchy and indexArtwork=auto:

Folder1
---Folder2
------Folder3
------Folder4
---Folder5
------Folder6

and if Folder4 and Folder6 have artwork, the artwork from Folder4 would be shown for Folder2, the artwork from Folder6 would be shown for Folder5 and the artwork from Folder2 (originally from Folder4) would be shown for Folder1.

If indexArtwork=auto is not set, only Folder4 and Folder6 would show artwork.

This is similar to how indexArtwork works for index menus (look for an image inside the index entry contents and show it for the index entry).
