Patch for GtkCList justification enhancement

[James Macnicol <jamesm evans ee adfa oz au>]

	The following patch introduces a new API called
gtk_clist_set_column_justification_full that allows you to modify the
justification of a column title of a GtkCList independently of the
body of the widget.  The behaviour of the existing API
gtk_clist_set_column_justification is unchanged.

	I'm submitting this because I think centered titles look much better
than left-justified ones, even if the body of the CList is left-justified.
