[Zope-PTK] Getting the latest PTKDemo/Document.py to work with Zope 2.3.0

[Jeffrey P Shell]

Zope 2.3 introduced the concept of "Declarative Security", and some Portal
Content objects have started to make use of this.  However, in Zope 2.3.0,
the ClassSecurityInfo class has a small bug in it that's exposed by the
current PTKDemo/Document.py.  This bug is fixed in the CVS HEAD and
zope-2_3-branch, but will affect those using the 2.3.0 release.

The fix is a one line change, in lib/python/AccessControl/SecurityInfo.py
line 245.  Change 'tuple(roles)' to 'tuple(roles.keys())'.

This fix will be in Zope 2.3.1, which is nearing a beta release.
