    commit-paned: Use a GtkActionBar for the commit tool bar
    
    Uses a GtkAction bar rather than a GtkFrame and a GtkBox to implement
    the commit tool bar. This better fits the role of this bar, avoids
    having double borders on the sides and the bottom, and dropd some custom
    styling.
