More info in utm cookies and rewrite values possibility

Since version 2.0.2 you can add more allowed cookies keys (save other info than just utm values) and you can rewrite cookies with your own values just with call UtmCookie::save($array) where $array should contains keys allowed by UtmCookie::$allowedUtmCookieKeys (default are allowed utm parameters names, but you can set it as you need). See examples for more info.
