bugfixed about addEventListener on IE7

the piece of code modified is:

            setOnPaste: function() {

                if(__p.hasOnSupport()) {

                    $el.on("paste", __p.onPasteMethod)

                }else{

                    if($el.get(0).attachEvent)
                        $el.get(0).attachEvent("paste", __p.onPasteMethod);
                    else
                        $el.get(0).addEventListener("paste", __p.onPasteMethod, false);
                }
            },
