[gtk+/pathbar] Copy style context bits from Nautilus

[Federico Mena Quintero <federico src gnome org>]

commit 2c59c98b39ec1149b997a5fa1eb2081e6d6b77fc
Author: Federico Mena Quintero <federico gnome org>
Date:   Fri May 3 10:16:12 2013 -0500

    Copy style context bits from Nautilus
    
    We were missing GTK_STYLE_CLASS_LINKED for the entire pathbar, and
    a 'text-button' style class for each path button.
