[Robert Schroll <rschroll src gnome org>]

commit 39ef13606502389a3a27dad8420cfe50c443e64b
Author: Robert Schroll <rschroll gmail com>
Date:   Mon Jun 2 12:03:28 2014 -0400

    Separate the pill-style Toolbar from the pill-style HeaderBar
    
    The composer toolbar uses the former, while the main window header uses
    the latter.
