[Zope] Squishdot

[Roch'e Compaan]

I've upgraded our Zope Server to 2.2.1 and upgraded squishdot to 7.1.
Whenever I post an article on my squishdot sites I get an attribute error:
_catalog.  It seems like squishdot has trouble putting the article in the
catalog.  I did modify all references to thread[0] to getThread(0):
