[gtk/gbsneto/filechooser-column-view: 161/161] filechooserwidget: Remember sort columns and order

[Matthias Clasen <matthiasc src gnome org>]

    filechooserwidget: Remember sort columns and order
    
    These settings existed before, we keep using them.
    This loses some information about sorting by multiple
    columns, but it is sufficient to get the same primary
    sort column back.
