A recent fix in the zope 3 traversing code now requires the ITraversable

adapter to be present even when traversing just dicts. No problem, we can
set it up quite easily.

This basically finishes this branch. All tests pass, some 3rd party apps
have been tested with it. There are a few test failures in the CMF and
others (e.g. Plone), but that's mostly "their fault" (incorrect or
unexpected usage of certain things).
