[Zope] Sending DB data via SESSION manager

[Chris McDonough]

I don't know exactly how to do this with formulator, but the SESSION
object implements all the methods that a dictionary does.  Which means
you can for all intents and purposes access it like a dictionary.  The
'update' method might be what you want here.
