Update css-validator.jar

With the example file screen.scss
>@import "compass/reset";

I obtains the following error when I validate it :
>invalid css/screen.css
>************************************************************
>Result: Invalid
>1 file validated.
>1 error found in 1 file.
>Somewhere, a kitten is crying.
>************************************************************
>Output from: css/screen.css
>{output=text, medium=all, warning=2, profile=css3, lang=en}
>W3C CSS Validator results for file:css/screen.css
>Line : 53 q:before, q:after, blockquote:before, blockquote:after
>       (Value Error : content (nullgenerate.html#propdef-content))
>       none is not a content value :


And it's validate with the update.
