	* python/dbus.py:

	Add ObjectTree class which allows implementation
	of trees of "virtual" objects. Basically the python
	wrapper for "register_fallback".

	* python/examples/Makefile.am
	* python/examples/gconf-proxy-client.py:
	* python/examples/gconf-proxy-service.py:

	Implement a simple GConf proxy service that supports
	get/set on string and int GConf keys using the ObjectTree.
