examples: update python examples

Update the raw D-Bus python examples to use newer APIs where
appropriate (and split the add-connection example into 1.0-only and
0.9-compatible versions). Update the gi-based python examples for the
various API changes since they were last updated.

Also add a comment to the ruby add-connection example pointing out
that it's still using the old settings APIs.
