Destroy the cursor after we have assigned it to the window -- there is no

	* gtk/gtkpaned.c (gtk_paned_realize): Destroy the cursor after we
	have assigned it to the window -- there is no point in keeping it around.
	(gtk_paned_unrealize): No need to destroy the cursor here.

	* gtk/gtkpaned.h (struct _GtkPaned): Removed the cursor field, as
	it is not needed.
