Add Composer to start of MinimServer Group, this is used by MinimServer for playing Classical Works

When you play a Classical work with MinimServer uPNP server enabling this option will show the composer when you play the group corresponding to the work. This can be very usual for distinguishing between completely different works with very similar names written by different composers. Because MinimServer only allows groups for work containing multiple contiguous movements enabling this option also includes adding the composer to title if the work has no movements.
