    AppChooser: Select app when row is activated
    
    This allows the user to select a startup application by double clicking
    on it rather than having to select it and then click on the ‘Add
    Application’ button. If there are now rows visible then GtkListBox will
    activate the (hidden) selected row so we need to check that the
    activated row is mapped.
