[Zope-DB] Automatic capture of user ids for auditing

For me, changing DA seems to add 'audit' fields seems nasty. What if you
will have one specific table that doesn't need audit fields (this may
happen when you're using authentication sources that rely on DB and in 
many other cases).

I think that much cleaner might be to create something like
AuditEnabledZSQLMethods that will render to sql that contains necessary
statements and use it instead of ZSQLMethods when necessary.

Above assumes that you'll create a Zope Product that (possibly) inherits
from ZSQLMethods. You may take a look at CCZSQLMethods as they are
example of extending ZSQLMethods.
