Trent Mick 37a1447f22 per issue change the way a raw stream is handled
"raw" is now a stream "type" isntead of a separate attribute. The
idea is that writing raw objects (instead of JSON-stringified stings)
to, e.g. a file WriteStream isn't useful. So, lets re-use the stream
"type" field instead of an additional "raw" field.
