I am using bootstrap 3 and jQuery version 1.10.2

I am also using easy commenter and they require jQuery version 1.5.2 I have tried to just keep version 1.10.2 , just keep version 1.5.2 and keep both of them. But in every case one of them does not behave as expected. With version 1.5.2 the collapsible menu in header stops working with version 1.10.2 easy commenter stops working. How should I deal with this problem?
Here is a link to the page I am working on <http://8mags.com/lessons/php/phpcalendar.php>
