	* gtk/gtklabel.c (gtk_label_class_init): Add a gtk-label-select-on-focus
	setting.
	(gtk_label_grab_focus): And use it here to select the contents of
	the label when appropriate.
	(gtk_label_class_init): Use the same keybindings for select all/
	unselect all as GtkEntry and GtkTextView.

	* gtk/gtkdialog.c (gtk_dialog_map): When looking for the initial
	focus, avoid leaving a selection in a label.
