[Zope-CMF] Login/logout information

[Ben Riga]

>>>>
You would need to tweak / override
'CMFCore.CookieCrumbler.CookieCrumbler.setAuthCookie' such that
it appends 'expires="Never"' to the call to 'resp.setCookie'
(line 153).

I tried making this one change and it really messed up the login cookie.
CMF started getting really confused about whether I was logged in or not.
I'm backing the change out.

Having looked at the CookieCrumbler code a little closer, it looks like this
setting is used at least a few other places.  I'll study the code and then
try to make the change.

Thanks,
Ben
