[Murray Cumming <murrayc src gnome org>]

commit 070e73810426f5e5d0d1bb7cc93520173d7e044e
Author: Murray Cumming <murrayc murrayc com>
Date:   Wed Mar 10 12:44:51 2010 +0100

    Window: Added unset_transient_for().
    
    * gtk/src/window.[hg|ccg]: Added unset_transient_for() now that the
        documentation of the C function says that an arg can be NULL and what it means.
