Allow external plugins to return no value
Instead of using the XML-RPC v2 extension <nil/>, which Perl's XML::RPC::Parser does not (yet) support (Joey's patch is pending), we agreed on a sentinel: {'null':''}, that is, a hash with a single key "null" pointing to the empty string. The Python proxy automatically converts None appropriately and raises an exception if a hook function should, by weird coincidence, attempt to return {'null':''}.
