I've made the current code base GSEAL compatible. The one function unable to be ported is Gtk.Widget's is_toplevel, which gtk+-2.0.vapi still translates into GTK_WIDGET_TOPLEVEL. When we use gtk+-3.0.vapi, that will be fixed. But for the moment, I commented out the additional check (which should be harmless in practice). So we're good for now.
