Please let this default to False. I wonder if it's better to have a separate
method that does the skipping. allowedContentTypes may be used by other
things already. Plone uses it in a few places, for example. :)

I don't suppose there's a way to make all FTI's expose actions, and just
construct an appropriate fallback URL (e.g. createObject or whatever) if no
add view has been specified? That'd mean folder_factories could just loop
through the actions.

+0 - Plone would need this in its content menu implementation, but that's
custom anyway.
