Glen Fraser 783b8b7361 In to_json(), maintain the "type" of empty maps and vectors
- fix issue #399.
- make to_json() with an empty Map, Vector or Dynamic_Object return a
  similar/compatible type (JSON object or array), rather than "null".
- include the fix for #381 (to_json() support for null values), so
  that can also be unit tested.
