11	* AJAX command for updating the value of a hidden form_build_id input element
12	* on a form. It requires the form passed in to have keys for both the old build
13	* ID in #build_id_old and the new build ID in #build_id.
14	*
15	* The primary use case for this Ajax command is to serve a new build ID to a
16	* form served from the cache to an anonymous user, preventing one anonymous
17	* user from accessing the form state of another anonymous user on Ajax enabled
18	* forms.
19	*
20	* This command is implemented by
21	* Drupal.AjaxCommands.prototype.update_build_id() defined in misc/ajax.js.
