  - AboutDialog: Add a constructor with a use_header_bar
    parameter(bgo#780004).

    to Glib::ustring, because there are always UTF-8.

    use_header_bar.
  - Dialog: Simplify the constructors: Remove constructors that
    take DialogFlags. Add an optional use_header_bar parameter to
    the other constuctors. There is now no way to specify the
    GTK_DIALOG_DESTROY_WITH_PARENT flag, but hopefully this is
    not used much anyway (bgo#780004).
