Appending .JSON is not required

[KamranSyed]

Appending .json in service url is causing client to fail. I have just removed it.

From the documentation you can see that

If no format option is provided, an attempt is made to extract it from the response Content-Type header.

Without the format option, no extension will be added to your url.
Just know that a lot of frameworks are using this functionnality to guess which content type use to format the response.

It would be a cool nice-to-have if appending the .format to the URL would be an optional switch, but let's not keep it a default. Making it the default caused confusion to a developer on a project of ours. I think removing it would be great.

Btw, I think that commenting the statement L157 makes the previous if block (that uses no brackets) apply itself on the next if statement (L162).
Correct me if I'm wrong.

EDIT : Remove typo
