Script cleaner can break down html

[asergiychuk]

If i meet something like that

    <p>.....</p>
    <script>
        some code ....
        document.write("<script src='some script'><\/script>")
        some code ....
    </script>
    <p>....</p>

cleaner remove many of html body

It can fix by chane code:

    $str = preg_replace("'<\s*script[^>]*[^/]>(.*?)<\s*/\s*script\s*>'is", '', $str);

to

$str = preg_replace("'<\s*script[^>]*[^/]>(.*?)<[^\/]*/\s*script\s*>'is", '', $str);

I could not duplicate the issue, I added a test in the commit above but, using the string you gave me, I am getting the correct result.

If you could provide a test case that fails and shows the issue, please create a pull request so I can fix it (or you could fix it and submit a pull request + test).

Thanks.
