[Zope] nested dtml-with

[Max M]

Don't do recursion in dtml. It's a cardinal sin, and it will make your 
head explode.

Do it in a Python script instead.

untested::

    def subTree(context, type=None):
        """
        Returns the entire sub-branch below this recursively as a flat list
        """
        children = context.objectValues(type)
        grandChildren = []
        for child in children:
            grandChildren += child.subTree(type)
        return children + grandChildren
