Everything inside <script> (also <style>?) has to be escaped automagically

[Altai-man]

JS bits containing <, e.g. a simple for loop or a condition are parsed as opener tags resulting in a failure:

                if (month.length < 2)
                    month = '0' + month;
                if (day.length < 2)
                    day = '0' + day;

leads to

    Template parse failed: malformed tag at line 54 near '< 2)
                        day = '0' + day'
