django.contrib.messages failing silently in safari when comma is used in message

[Sean Brant]

If you try and send a message with new messaging app that contains a
comma in the message it does not work in Safari.

I'm not really sure why the json encoded message is not working in the
Safari browser, but I fixed it by adding a base64 encode and decode
step that encodes/decodes the message string.

def _encode(self, messages, encode_empty=False):
...
if messages or encode_empty:
for message in messages:
message.message = base64.b64encode(message.message)
encoder = MessageEncoder(separators=(',', ':'))
...

def _decode(self, data):
...
messages = json.loads(value, cls=MessageDecoder)
for message in messages:
message.message = base64.b64decode
(message.message)
return messages
except ValueError:
pass
...

Sorry should note, this happens when using the CookieStorage backend.
