------------------

- fix `readonly` fields in `DictRowConverter.toFieldValue`.

- Remove obsolete `GridDataConverter` and use default `z3c.form.converter.MultiConverter`.
This now calls the `DictRowConverter` and translates all columns to their correct widget/field value.

- Add JSON deserializer for `plone.restapi`.
[petschki]
