[Zope] Test if document does exist

[Farrell, Troy]

You can check if the parent (usually a folder object, unless we are in a
DTML Document, not a DTML method) has the special document object attribute.
(tested)

<dtml-if expr="_.hasattr(PARENTS[0], 'special_document_name')">
  We have special_document
<dtml-else>
  No joy.
</dtml-if>

This doesn't render the document or check to see if any of it's contents
will raise a KeyError.
