[FIX] website, mass_mailing: restore original FieldTextHtml widget -> FieldTextHtmlFrame only for mass_mailing

The new `summernote in iframe` version of the
FieldTextHtml widget is not ready for prime time
yet.
Usability is not very good when used as a replacement
for the previous html editor, especially in email
composer windows, and initial loading is very slow.

For now we only enable it as FieldTextHtmlFrame for
mass_mailing templates, where isolation of the
style is important (so that recipients receive the
exact same result as was displayed on screen, without
side-effects caused by backend/frontend style)

In master the summernote version will be improved
and the old CLE version will be dropped completely.
