Hide the mouse cursor in the completion feedback window

2008-03-13  Federico Mena Quintero  <federico@novell.com>

	* gtk/gtkfilechooserentry.c (create_completion_feedback_window):
	Set the mouse cursor of the feedback window to invisible, so that
	we respect GtkEntry's invisible cursor while typing.
