v0.2.0

Requires contenir/contenir-extension-api 0.7.1 or later.

Changed

• Delete form is drawn as a destructive operation, apart from the rest: it takes the form, its fields,
  notifications, integrations and every entry. It still asks first.
• Fields, rows, validators and conditions are dragged on Parallelogram's drag engine (@parallelogram-js/core
^0.7.22) in place of SortableJS, which is no longer required. A row and a list of rules move up and down only;
  a field moves across as well, between columns and rows. A reorder posts only when a drop changed the order, and
  every row's field strip shows it can take a drop only while a field, not a row, is dragged.

Removed

• The add-on's own [data-identifier] component. The CMS registers that selector itself, so it left the add-on's
  out with a console warning; a field's ID now follows its label through the CMS's component alone.
