Since gtk+ is an object oriented toolkit (it is, right?), the proper way
(and way we have solved it here) is to create a subclass of GtkNotebook,
override the default switch-page handler, and only call down to the base
handler (that actually switches the page) if your validation allows the
switch. Otherwise, just return out of your new default handler.
