Display Track Artist instead of Album Artist

[simbun]

The settings work for the track listing in the WHA but not the Now Playing screen where it pulls metadata from the file being served (assuming it's not being transcoded). If you watch carefully, the screen loads initially with the correct metadata then updates with the tags from the file.

I have raised a ticket for this, but there's been very little development/bug fixing in this area for quite some time now. BubbleUPnP is definitely the way to go.
