Nginx::Request#content_type doesn't return Content-Type of request

Nginx::Request#content_type doesn't return Content-Type of request.

It looks Nginx::Request#content_type() and Nginx::Request#content_type=() are for HTTP response, not HTTP request. Very confusing name to me.

        location /foo {
          mruby_content_handler_code '
            r = Nginx::Request.new
            Nginx.rputs "content_type: " + r.content_type
            Nginx.return Nginx::HTTP_OK
          ';
        }

% curl -v -H "Content-Type: text/plain" http://127.0.0.1:58080/foo

Thank you for your opinion. Do you have ideas about names?

@matsumotory Can you give me some time to think about it?

I'm have been improving docs/class_and_method/README.md on https://github.com/yyamano/ngx_mruby/blob/doc-improvement/docs/class_and_method/README.md and playing with unfamiliar methods.
I'd like to get a clear picture before renaming.

Yes! Thanks always.
