[Murray Cumming <murrayc src gnome org>]

commit 4b6cd21808000664345ef94f17c972b88988f25e
Author: Murray Cumming <murrayc murrayc com>
Date:   Tue Feb 8 10:51:20 2011 +0100

    Entry: Added unset_icon().
    
    * gtk/src/entry.[hg|ccg]: Added unset_icon() because the
    gtk_entry_set_icon_from_*() functions do that when they are passed a NULL.
    Bug #621742 (feuloren)
