Title: Respect new requests behavior by not passing None-valued parameters.

Prior to requests 0.13.7, requests ignored None-valued query
parameters. Starting in 0.13.7, it includes these in the query string
as the string None. This works around the new behavior by simply not
including query parameters if they are None.
