Remove XML comment around JavaScript code

Internet Explorer throws an error if JS code is in XML comments when run through jQuery.globalEval on jQuery > 1.6.x (Plone 4.3.x). This is a problem in Plone with popupForms like the login form which do an AJAX request and then run all code on the result through jQuery.globalEval.
