moved rewritten testgtk demo here

2001-03-30  James Henstridge  <james@daa.com.au>

	* examples/pygtk-demo: moved rewritten testgtk demo here

	* gobjectmodule.c (pygobject_set_property): initialise the GValue
	to { 0, }, so set_property actually works.
	(pygobject_get_property): same here.

	* gtk/gtk.defs: updated enum/flag defs.

	* gtk/gdk.defs: updated enum/flag defs.

	* examples/gobject/signal.py (D.do_my_signal): add small example
	of overriding class closure for a signal introduced from python
	code.

	* codegen/h2def.py: add --onlyenums flag to only output enum defs.
