[gtk+/bgo593793-filechooser-recent-folders-master: 4/20] Put the pathbar in the 'Save in folder:' row in Save mode

[Federico Mena Quintero <federico src gnome org>]

commit 1ffd36814a6c5e5837a5ea65ebb28412133b6771
Author: Federico Mena Quintero <federico gnome org>
Date:   Tue Jun 28 15:21:49 2011 -0500

    Put the pathbar in the 'Save in folder:' row in Save mode
    
    Now we reparent the browse_path_bar_hbox to that spot in Save mode,
    or to be above the file lists in Open mode.  The pathbar makes for a very
    clear indication of the location to save in.
