CB Paid Subscriptions

Currently customer objects are created then reused, but not updated. They should be updated if any of the users data should change. Such as email address, name, etc.. It just needs to check this during getStripeCustomer when it's validating the customer id simply also check if the data has changed so we can see if we need to update the customer object. This isn't critical for functionality, but would be nice for records at Stripe.
