Webkit vbufBackend: Render labels for the preview song buttons in music tables in the iTunes store. Specifically: Fallback to rendering content from accDescription if accName and accValue are empty. Also rather than just checking if accName/accValue gives back a NULL pointer, actually check if the string is empty as well. Webkit seems to return 0-length strings for accName sometimes.
