copy support for portal_actions

Hi,

I have found a large problem in pickling my Plone sites.  There would
seem to be a python function embedded in portal_actions:

Doh - failed to copy
http://localhost:8080/last-bastion.net/hosting/A000003/balclutha.org/mgmt/portal_actions
Traceback (most recent call last):

~    raise TypeError, "can't pickle %s objects" % base.__name__
TypeError: can't pickle function objects

This can also be recreated when trying to paste one of these between sites.

Does anyone have any advice as to a fix??
