Display Track Artist instead of Album Artist

Thanks for this useful information. I have checked this and the BubbleUPnPServer server proxy uses a slightly different order when sending metadata items to the control point. The order should not make a difference for control points that implement the UPnP protocol correctly but it seems that it does make a difference with MusicCast.

I will change the order in the next MinimServer update and see whether this causes any problems for users with other control points.
