Fix too-new gtk_dialog_get_content_area function of r18413:

Patch by J. Alex Aycinena:

‘gtk_dialog_get_content_area’ is from GTK version 2.14. The attached
patch uses the prior '(GTK_DIALOG(dialog)->vbox)' in place of
'gtk_dialog_get_content_area (GTK_DIALOG (dialog))' and compiled
successfully on my GTK version 2.16 and the application operated
properly.
