The <child internal-child=""> thing is used for children that are
created as part of the parent, and always exist (so don't need to be
created by Glade/libglade). GTK+ has builtin support for these as well.

For some things like notebook tabs, expander labels and frame labels
this doesn't work, since the widgets may or may not exist and there may
be several of them. So we currently use the "type" packing property as a
slight hack.
