[web-annotation] Add reference to CORS

AFBarstow has just created a new issue for 
https://github.com/w3c/web-annotation:

== Add reference to CORS ==
The protocol spec refers to CORS but there is no reference to that REC
 in the references (<http://www.w3.org/TR/cors/>).

See https://github.com/w3c/web-annotation/issues/44
