Cannot connect to db with authentication

Passing username and password arguments to connect fails with :

motorengine.connection.ConnectionError: Cannot connect to database main :
Unknown option username

According to Motor manual the MotorClient should be created with uri for authentication :

uri = "mongodb://user:pass@localhost:27017/database_name"
client = motor.MotorClient(uri)

Hmmm... can you help us with a PR? I'm having a hard time to keep up with all the projects...

[partyzan]

Did some more testing based on the code and PyMongo documentation - authentication works when using mongo URI to connect as the host:

motorengine.connect(db=name, alias=alias, host="mongodb://username:password@127.0.0.1:27017", io_loop=tornado.ioloop.IOLoop.instance())

So only documentation should be updated :)
