Upgrad sarissa and avoid MSXML blocking ActiveX in IE 7

[ksgeograf]

In ajaxmappane.templ, line 2512 the following code is found:

function CreateRequestHandler()
{
    if(msie)
        return new ActiveXObject("Microsoft.XMLHTTP");
    else
        return new XMLHttpRequest();
}

This does not work in IE 7, where ActiveX is disabled. IE 7 has a built in XMLHttpRequest so the specialization does not make sense for IE 7. Further, the included Sarissa includes a wrapper, so IE 5 & 6 can also use a XMLHttpRequest without the special case. In short, the above code can be reduced to:

function CreateRequestHandler()
{
        return new XMLHttpRequest();
}

I have also tested the most recent sarissa (0.9.9) and it works without modification. The current version is 0.9.6.1.
