Default API response type: XML -> JSON
I thought it would be good to move from XML to JSON by default in the
response of the API if no response type is sent to the server along with
the request. I'm wondering that's the opinion of people on the mailing list.

If this change would cause more trouble, or is not needed in your opinion,
I don't mind to close the PR.
