Add a port of the 2.x version of the JSON databinding. This works with the JSONP binding. If I apply the 2.x changes to the existing JSON databinding the I can get the JSONP binding to work but it messes up other bindings, e.g. JSONRPC, which rely on it. These other bindings have been changed for 2.x also. Not in build yet.
