Expose private teams through the API

[Łukasz Czyżykowski]

Current API only allows to access public teams and there's no way of obtaining private teams memberships.

QA notes:
Currently deployed on EC2: http://ec2-174-129-73-160.compute-1.amazonaws.com
This code adds new method: api.authentications.team_membership(team_names, openid_identifier).
It's part of the API and should be tested in the same way as previously. Attached to this bug is list of existing teams and accounts on the server.

I don't get any obvious errors doing what I was told to do.

I'll talk with Lukasz some more on Monday to be certain.
