Outputs invalid HOCON/JSON/YAML

[pauldraper]

There is insufficient escaping of outputs.

Conversion example

regex: "[0-9]\.[0-9]*"

used to produce

{
  "regex": "[0-9]\\.[0-9]*"
}

but since #173 now produces malformed

{
  "regex": "[0-9]\.[0-9]*"
}

which is invalid.

The HOCON is probably invalid too (IDK), but in any case the Python API will have the same problem.

It looks like the json converter doesn't handle a lot of cases.

Compared to the Python json converter.

Is there a reason that the json module is not used?

Should this be closed now that #202 is merged?
