[gtk+/gtk-2-24] filechooserentry: Use a GtkFileFilter for filtering

[Federico Mena Quintero <federico src gnome org>]

    filechooserentry: Use a GtkFileFilter for filtering
    
    That way, we can use the regular filtering features of the
    filesystemmodel instead of having our own filtering function that
    duplicates much of the matching code.
    
    This also removes the broken-on-windows feature where files strting with
    a dot were not autocompleted.
