for passing in the dbus message as keyword for edge case signal handling * python/matchrules.py (SignalMatchRule.__repr__): fix output to conform with what dbus expects for match rules (SignalMatchRule.execute): add the dbus message as a keyword if the signal handler has requested it * python/examples/example/signal-recipient.py: added some more examples on how to hook up to signals * python/proxies.py: minor formatting changes
