[validator] UrlValidator fails http://www.google.com

Per discussion on commons-dev list the following isValid method should not
return false for http://www.google.com;

public void testSanity() {
UrlValidator v = new UrlValidator();
assertTrue(v.isValid("http://www.google.com"));
}

Bug/enhancement I think is to make port and path optional tokens of the url.
