Re: [paymentrequest] Constructor should not include "total" in list of items (#68)

In the spirit of stimulating further discussion, I shall disagree with that point. Sometimes from the user's perspective the total is the *last* thing that matters. This is because some types of payment instrument - such as an EMV card - require an absolute amount to be charged (the 'total'). However, this absolute amount may have little to no bearing on the expected cost of the product (an Uber or Lyft pre-auth, for example).

>From the payment provider's perspective, the total may well be the only thing that really matters. That is not true from the user's perspective.
