    Change packing of pulsebar in statusbar (#7)
    
    The pulsebar looks very small and needs to be widened.  The pulsebar is
    packed inside the statusbar so that it displays activity text on the
    left side and the pulsebar on the right side.  Ideally we want the space
    to be evenly divided for the textual messages and for the pulsebar
    activity indicator.
    
    For this we just have to set the 'homogeneous' property to TRUE for the
    statusbar (note that GtkStatusBar inherits from GtkBox).
    
    Also vertically align the pulsebar to the center of the statusbar.  This
    is achieved setting the 'valign' property to Gtk::ALIGN_CENTER for the
    pulsebar widget.
    
    Closes #7 - Port to Gtk3
