- New option for all form_fields: "disabled_as_div" to render disabled input fields as div. This has the advantage that con can provide with little effort highlighting in such fields. - New conveniance method "is_disabled" to avoid repetitious cose - Additional correct_when predicate: "contains". Correct, when answer contains any of the provided words.
- added instance variable parent_field (when create_components is used). This eases the upwards traversal for compound form fields.
- simplify usage of shuffling since it makes configuration via form-constraints easier. we use now one field "shuffle_kind" instead of the tow fields before.
