[cors] CORS module

# Summary

Cross-origin resource sharing (CORS) is a mechanism that allows a web page to make XMLHttpRequests to another domain. Such "cross-domain" requests would otherwise be forbidden by web browsers, per the same origin security policy.

This module provides a configuration page to map domains to paths and add the necessary Access-Control-Allow-Origin header.

CORS is aimed to be a solution until this: https://www.drupal.org/node/1869548 will land in core.
