Don't clamp the restored size of the file chooser dialog

Don't clamp the restored size of the file chooser dialog
	* gtk/gtkfilechooserdialog.c
	(file_chooser_widget_default_size_changed): Simply resize the
	dialog to the default size without any fancy clamping.  Also,
	leave in place ifdef-ed out code to restore the file chooser's
	position in addition to its size.  The code to restore the
	position doesn't quite work yet, but we'll leave it in as a
	reference.
