numerical arguments with defaults of 0 are passed as None

[Doug Hellmann]

With a controller that takes integer arguments defaulting to 0, if the value is not passed in the request the controller receives None instead of 0.

For an example of a controller like that see http://paste.openstack.org/show/73192/

    is provided in the request, the controller is being passed None instead
    of 0.
