Title: Handle logging of Buffer meta data

Buffer objects were previously stringified in an extremely space consuming format ( they looked like {"0":"124", "1":"0", "2":"36", …, "readUInt32BE": {}, ...}).

This commit serializes buffers as base64 strings.
It also ensures that objects that are serialized do not have their functions serialized as empty objects.
