    GtkComboBoxText: Improved GtkBuildable documentation.
    
    Also removed a bogus FIXME comment which might have been true
    a long time ago. Clarification: the "domain" attribute specified
    in the builder script overrides any domain previously set with
    gtk_builder_set_translation_domain(), so the translation of items
    here is perfectly correct and does not need to be fixed.
