Schema fields don't work with PersistentList and Dict

[Damien Genet]

PersistentList & PersistentDict aren't valid types for List & Dict schema fields. For instance the following code fails (where IKLass is a zope.schema.List) :

class Klass(Peristent):
    list = FieldProperty(IKlass['list'])

    def __init__(self):
        self.list = PersistentList ()

The intent of the patch looks reasonable, although it doesn't apply cleanly to the current zope.schema trunk. However, the patch needs to be extended with new tests showing the use of the new PersistentList / PersistentDict types.
