Ok. I checked in all my local changes. AFAICS everything works fine, but
tests are still missing.
Please note that so far only File has a full add view. All other content
types use the fallback add view.
I still use the pattern that adapts ITypeInformation as well. Our add
views are anyway Zope 2 specific, so I don't think requiring explicit
Zope 2 security declarations is unacceptable. All other solutions have
also their drawbacks.
