[Zope] using a ZCatalog via xmlrpc

[Andreas Jung]

The data returned by searchResults() can not be marshalled since
they contain non-basic data structures like IOBTreeItems that can not
be transported using XMLRPC. I suggest to wrap the searchResults
into a PythonScript or an external method and convert the result
to basic datatypes likes lists, dictionaries ....
