Track Info [Playlist] field: Add playlist name

For any selected track that is part of a playlist,
additional info about the list is now provided in
the [Playlist] field of the Track Info screen.

1) Asterisk indicates if playlist has been modified.
2) Playlist filename is visible, unless the current
playlist is *not* associated with a file on disk, in
which case the following will be shown instead:

- (Folder)    for unmodified folder playlists.
- (Dynamic)   for playlists that are neither associated
              with a playlist file, nor with a folder.
