[gtk/gbsneto/filechooser-column-view: 20/74] filechooserwidget: Move folder navigation to column view

[Matthias Clasen <matthiasc src gnome org>]

    filechooserwidget: Move folder navigation to column view
    
    React to column view's 'activate' signal, instead of treeview's
    'row-activated'. It doesn't handle file sensitivity yet, but that
    will probably be dropped later.
