    Fixup: added an informative column (bgo#732339)
    
    This column may be useful so other extensions that use the
    MetadataFixer can give more info about the track being fixed
    (current solvers of this extension can fix many tracks per
    row, so this may not be useful for them, because using just
    a cell to show information about more than one track may be
    ugly; but the solvers being developed in b-c-e mostly add
    one-fix-per-track solvers, therefore the HasTrackDetails
    property will be marked as FALSE by default, but virtual,
    so derived classes can override it).
