Add new "gtk-theme" property to <greeter> tag theme xml format, so the

2006-02-21  Brian Cameron  <brian.cameron@sun.com>

        * gui/greeter/greeter_parser.c:  Add new "gtk-theme" property
          to <greeter> tag theme xml format, so the theme can specify a
          GtkTheme to be used for gdmgreeter.  This allows theming of
          the "Options" menu and the entry field, and any other GTK+
          widgets used by gdmgreeter.  This also makes it possible to
          create a11y themes (HighContrast, LowContrast, etc.) themes
          for gdmgreeter.
