Leftovers regarding modifiers in CanMakePaymentEvents

[SECtim]

Hi,

after I scratched my head for quite a while over why there are both methodData and modifiers, I stumbled across #289, which explained it for me. While this might be a candidate for some clarification in the specs (unless I overlooked an existing explanation), this issue is about the following lines in the Payment Handler API (both in the Can Make Payment section):

payment-handler/index.html

Line 912 in 4b4525f

<dfn>methodData</dfn>, and <dfn>modifiers</dfn> members share their

payment-handler/index.html

Lines 988 to 994 in 4b4525f

	<dt>
	<a data-lt="CanMakePaymentEvent.modifiers">modifiers</a>
	</dt>
	<dd>
	The result of executing the <a>Modifiers Population
	Algorithm</a>.
	</dd>

These seem to be leftovers from before #289 / #315 - if my understanding is correct, these should be removed as well.

Thanks!
