> The REST plugin's ContentTypeHandlerManager assumes the content-type of the request and content-type of the response are both determined by the request extension (eg. .json, .xml).
> However, a common use-case for browser user-agents is that the request content type will be "application/x-www-form-urlencoded" or "application/form-multipart" with a JSON, XML or HTML response content type.
> Proposal: split the ContentTypeHandlerManager to implement getHandlerForRequest() and getHandlerForResponse() methods. The request handler should inspect the request content type and give precedence to the handler for the content type first, falling-back to the handler for the extension if not found/not specified.  The Response handler will continue to use the extension (later it should use the accepts request header).
> Registration of ContentTypeHandlers will place the handler in the appropriate request/response handlers map depending on the extension (if present) and content type (if present). Overrides will still only apply to the extension at this time.
> This change will also add a new default ContentTypeHandler for "application/x-www-form-urlencoded" requests.
