[ADD] form_editor: whitelisting of fields

Automatically whitelist fields added to a website_form through the form
editor.

Ideally fields *removed* from a form should be removed from the
whitelist, but since we don't/can't keep track of the website's form,
there's no way to know if a field is needed by multiple forms and thus
no way to remove them.

Plus that would require way more source-tracking than just whitelisting
all the form's fields, I don't know if snippet widgets can track the
removal of elements from a page (easily anyway).
