BACKWARD COMPATIBILITY BREAKS:
- jquery.js has been **removed** from widget.media, this means that you are
now responsible for ensuring that jquery is loaded in your page prior to
displaying the form (form.media).
- trailing dash was replaced by underscore in forward conf, ie.
dal-forward-conf-for-id_test becomes dal-forward-conf-for_id_test
