Python3 JSON Adapter byte string is not serializable

[Amorik]

Use of the python3 branch and the JSON adapter results in the following error:

TypeError: Object of type bytes is not JSON serializable

Im not very familiar with all of the code yet but it appears that the dictionary data being dumped by json.dumps contains values of byte/bytestrings/bytesequences. This was fine in python2 since it handled the encoding/decoding but that not longer happens on its own in the python3 version of JSON.

return json.dumps( data )

To resolve i switched from import json to import simplejson as simplejson can handle the bytes conversion. This might not be the right approach for this project, but either way the bytes objects needs to be UTF8 encoded to be JSON compliant/serializable.
