New features

This update started when adixon opened this import issue about privacy:

Warning! This release can break your form theming and AJAX will work incorrectly for multiple instance of the same form on the same page, including called via modal because of new static selector.

This done because current bug is much harder to fix. If there an AJAX element, and it was used, main AJAX for form called, but not replace old form, because build_id_old, on which AJAX previously rely, is changed by AJAX element. e.g. filed filed on AJAX form.
