Update to add new gconf requirement.

2003-01-14  Glynn Foster  <glynn.foster@sun.com>

	* configure.in: Update to add new gconf requirement.

	* src/zenity.h, src/about.c: Hurray for a new about box,
	although it lacks an icon. I wonder if people would actually
	like to see this as part of the dialog options. Can't think
	of any reason to do so at the moment though. Large chunks
	copied from libgnomeui/gnome-about.[ch]

	* src/util.h, src/util.c: Add new helper functions because I
	don't want to touch gnome_program with a bargepole. Copied from
	libgnome/gnome-url.[ch]

	* po/POTFILES.in: Add missing files. I think we have
	everything now.

	* TODO: Update accordingly.
