    thegamesdb: Add TurboGrafx-CD support
    
    Add TurboGrafx-CD support via the unregistered
    'application/x-pc-engine-cd-rom' MIME type as none is registered for
    TurboGrafx-CD discs, similar to PlayStation games.
    
    Also move both TurboGrafx-CD and PlayStation to a separate section.
