	Changing GtkFileChooserEntry to use GtkEntryCompletion.

	* gtk/gtkfilechooserentry.c (gtk_file_chooser_entry_init): Create
	a GtkListStore for the completion list.  Create a
	GtkEntryCompletion and attach it to the chooser entry.
	(gtk_file_chooser_entry_finalize): Unref the completion store.
	(completion_match_func): New callback for the GtkEntryCompletion.
	(completion_idle_callback): Fill the completion store with filenames.
