RESTFULLJSON should use query params for GET

[marcboon]

The RESTFULLJSON data type puts request parameters in the body of the request. This is not considered good practice, and some browsers (e.g. FireFox) won't even accept this. The fetch API doesn't execute GET request with a body. A proper RESTful request puts all query parameters in the query string and/or the path.

By the way: RESTFULLJSON is also misspelled, should be RESTFULJSON (one L)
