GApplication and GtkApplication oddness

[Richard Hughes <hughsient gmail com>]

With GApplication we have:

	application = g_application_new_and_register
("org.gnome.ColorManager.Prefs", argc, argv);

and with GtkApplication we have:

	application = gtk_application_new (argc, argv, "org.gnome.ColorManager.Prefs");

It does seem slightly odd that the former has the appid first, and the
latter has it last. I'm not sure it matters much, but I figured
feedback might be useful.

Richard.
