ie 9 visit dropthings, fast rss widget cannot load rss content

What steps will reproduce the problem?
1. ie 9 visit dropthings, fast rss widget error. caused by ensure.js is not 
compatible ie 9.

What is the expected output? What do you see instead?
rss cannot be loaded.

What version of the product are you using? On what operating system?
2.7.5 ie 9 + windows 7

Please provide any additional information below.

Since ie 9 support both 'onload' and 'onreadystatechange' event on element 
"script", logic in function createScriptTag() is not correct.
I changed it to 
====================================

        createScriptTag: function (url, success, error) {
            var scriptTag = document.createElement("script");
            scriptTag.setAttribute("type", "text/javascript");
            scriptTag.setAttribute("src", url);

            if (HttpLibrary.browser.msie) {
                 scriptTag.onreadystatechange = function () {
                    if ((!this.readyState ||
                    this.readyState == "loaded" || this.readyState == "complete")) {
                        success();
                    }
                };
            }
            else {
                scriptTag.onload == function () {
                    if ((!this.readyState ||
                    this.readyState == "loaded" || this.readyState == "complete")) {
                        success();
                    }
                };
            }

            scriptTag.onerror = function () {
                error(data.url + " failed to load");
            };
            var head = HttpLibrary.getHead();
            head.appendChild(scriptTag);
        }

====================================

work fine.
