From Murray Cumming.

* hildon-lgpl/hildon-caption.c:
	(hildon_caption_init): Do the hildon_caption_set_child_expand()
	here.
	(hildon_caption_new): Use the child property from GtkContainer
	instead of calling gtk_container_add(), because _new() functions
	should just use g_object_new(), so that language-bindings can do
	the same.

	* ut/hildon-widgets_tests.c: Added test42 for hildon_caption_new.
