Finally make the new converter work. API-wise it is as good as the old one (can import everyting, the old one could),
but design-wise it might be much more powerfull. Basically it can handle/convert all content-types for which one can
create an Add- or EditForm? successfully. In other words: if you manage to write an edit form for some content type,
then you can also create an importer for that content-type. Still finetuning needed (for dates, bool data, etc.) but
the main things work.

+        values. Values and keys have to be strings.
+
+        If `context` is a string, this is understood as a factory name
+        and we will try to create a proper object calling
+        ``createObject()``. If it is an object then we will update

+
+        `form_fields` are by default (``None``) buildt from the given

+        default. This might be handy if you want to omit or select
+        certains fields from the interface.

+        happened (errors that apply to several fields), and ``OBJ`` is
+        the created/updated object.
