tools (common/data_objects): added a "deserialise" argument to BlogItem: BlogItem is doing deserialisation itself, which is not clean (it should be done at bridge level), and which is causing trouble in jp which doesn't expect serialisation. As a workaround, the "deserialise" argument has been added for now (default to True), until deserialisation is properly managed in bridge.
