commit 8c2aa6c86d4e43932de6227436e6d1962e95abc9

    [ftinspect] Remove `QComboBoxx`
    
    We no longer need a custom `QComboBox` for disabling individual items in the
    combo box. Our custom `QAbstractListModel` has done this already.
    
    * src/ftinspect/widgets/custom_widgets.cpp,
      src/ftinspect/widgets/custom_widgets.hpp: Remove `QComboBoxx`.
