[Zope] ANNOUNCE: ZCache Product v0.2

[Itamar Shtull-Trauring]

ZCache 0.2 now generates 'Last-Modified' headers - I liberated the code from
the new Image.py.  So ZCaches should now be cached in browsers and proxies. 
If it's called from <dtml-var> it doesn't generate the headers, so it should
work correctly when embedded in other documents.  

This version also does basic permission checking.
