Feature suggestion: customise abum, title inside groups

[classical11]

The new version fully handles what I was after. I didn't even have to retag my library: by setting Title.displayFormat={$movement}, the movements appear as I want them when browsing the contents of a work.

I particularly like the fact that <upnp:album> is now sent to the control point with the Group tag for the tracks that are under a group.

This also has the nice added benefit that the Album and Title tags shown in the Now Playing screen of the control point are much shorter but without losing any useful information.

Thanks very much for the changes and for implementing them so quickly!
