    appDisplay: Create AppFolderIcons for selected categories
    
    App folders are intended for grouping some applications, not to
    assign a category to every single application, so we will only
    create folders for a selected subset of the existing categories.
    Software/Alacarte will eventually allow to create/modify those
    folders, so store the setting in GSettings so that it can be
    shared with those applications.
