[Zope] ZClass inheritance and properties (Zope 2.3.0)

[Jim Washington]

Hi, Oliver

I believe that what you have done is overridden the parent's
propertysheet by making a new one in the child by the same name.
Whether that is the correct behavior is perhaps a matter of debate, but
in the current implementation of ZClasses, you need to use different
propertysheet names in parent and child in order for the child to access
the parent's propertysheets.
