plugin pubsub schema: values handling: - "schema" attribute can now be specified directly as a data_form.Form (reparsing it will be avoided in this case) - new "deserialise" parameter allows deserialisation from unicode strings in sendDataFormItem - values can now be an iterable or directly the value to use (it will be put in a list automatically in the later case) - "id" is now put directly in XMLUI's "id" field instea of "_id"
