Make ThumbList work in IE10.

// Temporary fix for IE10 before we upgrade to ExtJS 4.2.

// Without this clicking on the icons of ThumbList will show blank

// page as the code won't be able to extract the value of ext:url

// attribute.

//

// Patch taken from forum:

// http://www.sencha.com/forum/showthread.php?250267-Ext.Element.getAttribute-not-working-in-IE10

Ext.override(Ext.dom.Element, {

    getAttribute: (Ext.isIE6 || Ext.isIE7 || Ext.isIE8) ?

        function (name, ns) {

            var d = this.dom,

                    type;

            if (ns) {

                type = typeof d[ns + ":" + name];

                if (type != 'undefined' && type != 'unknown') {

                    return d[ns + ":" + name] || null;

                }

                return null;

            }

            if (name === "for") {

                name = "htmlFor";

            }
