[0] Add CORS headers for updates

[luisherranz]

In order to be able to update WP from an external site (useful for scripts) we need to modify the CORS headers sent by the RESP API. These are:

function allow_origin() {
    if (!headers_sent()) {
        header("Access-Control-Allow-Origin: *");
        header('Access-Control-Allow-Methods: POST, GET, OPTIONS, PUT, DELETE');
        header("Access-Control-Allow-Headers: Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With");
        }
}

add_action('rest_pre_serve_request', array($this,'allow_origin'));
