[Zope-CMF] [dev] removing Zope2 interfaces

[yuppie]

Hi!


There are no deprecation warnings, but Zope2 interfaces are deprecated 
for quite a while now. CMF 2.0 and 2.1 should work without using any 
Zope2 interfaces in your own code or third party products. The BBB 
comments say they will be removed after CMF 2.1.

CMF 2.1 has a branch now, so if there are no objections I'll rip out 
Zope2 interfaces on CMF trunk.


Cheers,
