        XSSFilter should log to the console when it blocks something
        https://bugs.webkit.org/show_bug.cgi?id=53354

        This patch refactors a bunch of methods in XSSFilter to return a bool
        indicating whether they blocked anything.  Using this bool, we decide
        whether to log to the console.  We're using the same log message as the
        XSSAuditor, but it seems likely we can improve this message in the
        future (especially by piping in the correct line number, which is now
        accessible via the parser).
