[gtk+/composite-templates-new: 9/32] GtkDialog: Define children with a GtkBuilder template

commit 94315895be71f59ef0f459dc06b2e9a005dc3277
Author: Tristan Van Berkom <tristanvb openismus com>

    GtkDialog: Define children with a GtkBuilder template
    
    As the first composite widget in GTK+, this patch also
    adds some Makefile mechanics to list the ui files as
    dependencies of the global GTK+ resources, and adds the
    initial test case where composite classes should be tested.
