* python/dbus_bindings.pyx.in: Updated to handle new D-BUS type system

* python/dbus_bindings.pyx.in: Updated to handle new D-BUS type system
	- BUS_ACTIVATION -> BUS_STARTER
	- DBUS_BUS_ACTIVATION -> DBUS_BUS_STARTER
	- class MessageIter (__init__): Added recursion checking
	so we throw a nice error instead of just disconnecting from the
	bus.
	(get): Added arg_type parameter for recursion.
	Removed the nil type
	Added signiture type placeholder (not implemented)
	Added struct type placeholder (not implemented)
	Added varient type placeholder (not implemented)
	Commented out dict type for now
	(get_element_type): renamed from get_array_type
	(get_*): changed to use the dbus_message_iter_get_basic API
	(get_*_array): removed in favor of recursive get_array method
	(get_array): new recursive method which calls get to marshal
        the elements of the array
	(value_to_dbus_sig): New method returns the corrasponding
	dbus signiture to a python value
	(append): Comment out dict handling for now
	Handle lists with the new recursive API
	Comment out None handling for now
	(append_nil): removed
	(append_*): changed to use dbus_message_iter_append_basic API
	(append_*_array): removed in favor of recursive append_array
	method
	(__str__): Make it easier to print out recursive iterators
	for debugging
	- class Message (__str__): moved type inspection to the
	MessageIter class' __str__ method
	(get_iter): Added an append parameter wich defaults to False
	If True use the new API's to create an append iterator

* python/dbus.py: Update to use new bindings API
	- TYPE_ACTIVATION -> TYPE_STARTER
	- class Bus (_get_match_rule): GetServiceOwner -> GetNameOwner
	- class ActivationBus -> class StarterBus
	- class RemoteObject (__call__): get an append iterator
	- (_dispatch_dbus_method_call): get an append iterator
	- class Object (emit_signal): get an append iterator

* python/examples/: Fixed up the examples to work with the new API
