feat(JSON): support JSON as a first-class citizen in qri (#271)

lots of JSON support fixes. updated to go 1.10. This proves qri can do JSON. We've also added the capacity to have the top level of a dataset be an object. Also removed the now useless json.FormatConfig (it's all driven by schemas now).

unfortunately, it looks like I've shipped a small regression in dataset schema detection, which seems to now point out booleans as strings. I'll file an issue and fix.
