Updated "Basic Credit Transfer Payment" Specification

Hi Matt, Cyril, Kris, Vincent, Adrian, and Todd,

Based on our 16 December discussion  [1] I updated today:

 Basic Credit Transfer Payment
 http://w3c.github.io/webpayments-methods-credit-transfer-direct-debit/

Changes:

 * Structure aligned with Basic Card
 * New title of the spec
 * New payment method identifier: credit-transfer
 * New dependency on ISO 3611 for country codes (related to filtering)
 * New supportedCountries field (for filtering)
 * New section 6 (design considerations).

Not changed:

 * The repo URL
 * The request/response fields. Vincent will be looking at CGI later this month and sending us
   suggestions for fields (see [1]).
 * The flow diagram.

Comments welcome [2]. I suggest we meet next after 24 January (that is, after Vincent has
had a chance to review request/response fields).

Ian
