I expanded the branch by adding a proposed viewification for the Link  
content type, based on Tres' example and code he sent to me a few  
weeks ago.

As mentioned in Tres' note, the five:traversable configuration in  
CMFDefault/configure.zcml is commented out because it breaks other  
CMF tests and you neeed to uncomment it to see the new stuff.  
However, I am seeing breakage in the link views tests themselves  
(traceback below) which I can't quite interpret. This time I doubt it  
is due to a sandbox with old software, I'm working off today's Zope  
2.8 branch, the tseaver-viewification CMF branch and todays Five  
trunk. Can anyone spot what the problem is? Using the views in the  
browser does not show any error, it only pops up during testing.
