Got 2 errors when using roundup with Zope 2.8.5 (didn't test other releases) within 'ZRoundup.py'

The first bug was a missing method 'start_response', which i borrowed from 'roundup_server.py'

The second only appears when there are no items in FormWrapper, so iteration is not handled properly

With the followed patch against 'ZRoundup.py' roundup is now working in Zope2.8.5. I don't know whether this was the correct way to do this ...

<     def start_response(self, headers, response):
<         self.send_response(response)
<         for key, value in headers:
<             self.send_header(key, value)
<         self.end_headers()

Appled, thanks.
