The trouble is that things are transitioning now until Kevin decides
that Membership is OK.  Then what needs to happen is:

1. PTK requires Membership as well as LoginManager/ZPatterns.

2. DemoPortal.zexp is changed to use MemberMixin from Membership.

For now, I might try to replace the PersistentUserSource.py in PTKDemo 
with a dummy file that just imports the one from Membership to avoid
keeping the two in sync.
