DELETE responses send 200 status without any entity

[thboileau]

I've noticed that even if the delete method does not send back an entity, the status is 200 whether it should be 204 (no content) which sticks to the HTT RFC (http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.2.5): The server has fulfilled the request but does not need to return an entity-body

Should be extended to the other methods, and not only the GET method (as seen in the ServerResource#handle method).
