Removed unnecessary method renderResponseLine() on line 463 to 471, s…

…uggest using method renderStatusLine() on line 227 to 241 instead. I have also updated the toString() method, in the first line of the function from $str = $this->renderResponseLine() to $str-> = $this->renderStatusLine(), I also suggest changing from "\r\n" to PHP_EOL. Updates will be needed in Zend\Http\PhpEnvironment\Response to. Go look for comment on that aswell.
