* src/glade-utils.c: Open file in "a+" mode and not "w", which was
	  truncating the file only to check if it was writable ( ! doh ! )

	* src/glade-widget.[ch]:
	  o Added GladeCreateReason argument to glade_widget_new_for_internal_child(),
	    now internal children get post create functions called for them.
	  o Fixed bug 336581 (apply internal widget names at load time).

	* src/glade-gtk.c: Added per dialog support for dialog buttons
	  (get_children(), get_internal_child() && create internals in post_create())
	  (Fixing bug 337196)

	* widgets/gtk+.xml.in: Removed redundant declaration of glade_gtk_dialog_post_create()
	  in the GtkMessageDialog, added "get-children-function" support to GtkDialog.
