Title: Setting shipping address using the linkpoint gateway fails if the credit card object is nil.

When setting up parameters for the LinkpointGateway, if no creditcard object is supplied while trying to set the shipping address, you will receive a nil object reference for creditcard. This happens when attempting to access name property of the creditcard object.

I have added a fix, in the same fashion to the code for handling the billing address (which works)
