* New module gnosis.anon. This module generates "anonyms" for email
addresses, and forwards any mail sent to those anonyms on to the
corresponding real addresses. In other words, this is a protocol
that allows anonymous recipients to get email. Currently alpha-status.
See http://gnosis.cx/anon for further information.
* Updated gnosis.xml.pickle to handle the new BooleanType in
Python 2.3. Python <= 2.2 can read these pickles as well.
Revised family mapping for functions/classes.
* Bugfix in gnosis.xml.pickle.util for classes that are
loaded from sys.modules.
* Rewrote gnosis.util.introspect.instance_noinit to use more
robust "new" module and/or __new__() as applicable. Added
obj_from_classtype to public API.
* Updated xml.objectify to handle namespaces. Additional check
for passed DOM node. Added new tests.
* New util xmlcat.py for concatenating XML files.
