Ell 887d6a3670 app, themes: fix display-shell statusbar height 
In gimp.css, don't set a minimum height for GimpDisplayShell
statusbars.  Instead, in GimpStatusbar, set the widget's minimum
height to the maximum of its children's natural heights.  Note that
we have to do this manually, instead of using a size group, since
GtkSizeGroup::ignore-hidden is deprecated (and nonfunctional) in
GTK3.
