radio buttons don't work in IE7

See the reason here:

IE (at least versions 6 and 7) has a bug: it is not able to set properly the name attribute on using DOM methods, in case of the elements (like radio groups) which must have the same name. Another bug: IE is not able to set some properties (like checked) unless the element is already appended to the parent.

That also explains that other bug with checkboxes in IE7.

if (isIE)
    e=document.createElement('<input type="radio" name="group">')
else {
    e=document.createElement('input');
    e.setAttribute('type','radio');
    e.setAttribute('name','group');
}

Closing this since we're dropping IE7 support.
