[python-tulip] Present ZeroMQ integration and new Postgres client

[Andrew Svetlov]

I glad to present new libraries:
aiozmq -- integration with ZeroMQ sockets (http://aiopg.readthedocs.org)
aiopg -- Postgres client (http://aiopg.readthedocs.org)

Libs have good test coverage and some documentation.

While I have some plans for improvement of both libraries you can start to 
use it -- new versions will not break backward compatibility.

Thanks,
Andrew Svetlov.
