[Merge] lp:~brendan-donegan/address-book-app/contacts_dbus_service into lp:address-book-app

[Brendan Donegan]

Well the initial motivation is because it's easier to use via python, but I hear your reservations about compatibility. Perhaps adding some functional tests will protect against that? I can do that if needed. Of course I could also make a wrapper or something for the C++ API with python, but it's tricky and not something I'm experienced in.
