HtmlUnitDriver support for CSS 3 selectors

Originally reported on Google Code with ID 1298

What steps will reproduce the problem?

The following code attempts to use the CSS 3 :nth-child selector but fails with a TestCSSParseException:
--------------------------------------------------------------------------------
  public static void main(String[] args) {
    WebDriver driver = new HtmlUnitDriver(true);
    driver.get("http://www.google.com");
    WebElement td;

    // CSS 3 selector; currently fails with TestCSSParseException
    td = driver.findElement(By.cssSelector("form[name='f'] td:nth-child(2)"));

    // Ersatz demonstrating the correct behavior
    td = driver.findElements(By.cssSelector("form[name='f'] td")).get(1);

    System.out.println("Number of descendant <input> elements: " + td.findElements(
        By.tagName("input")).size());
  }

--------------------------------------------------------------------------------

What is the expected output? What do you see instead?
The above CSS 3 selector works fine when using, for example, document.querySelectorAll
in Firefox.  WebDriver throws the following exception:

Exception in thread "main" com.steadystate.css.sac.TestCSSParseException: Error in
pseudo class or element. Invalid token "2". Was expecting one of: <S>, ")", <IDENT>.
