No normalization of add/remove/toggle in IE10 and IE11

I tested the polyfill in IE10 and IE11 (Win7 on a virtual machine) and the functions still have partial support of classList. Multiple parameters in the add() and remove() functions still don’t work.

    if (!("classList" in document.createElement("_"))
        || document.createElementNS && !("classList" in document.createElementNS("http://www.w3.org/2000/svg", "g"))) {

The last condition !("classList" in document.createElementNS("http://www.w3.org/2000/svg", "g")) evaluates to true, so the part for no classlist support will be executed. The part for partial classlist supported browsers won’t be executed in IE10/11.

I could “fix” the issue by changing || to && in line18/19:

    if (!("classList" in document.createElement("_"))
        && document.createElementNS && !("classList" in document.createElementNS("http://www.w3.org/2000/svg", "g"))) {

It seems to work for IE10/11, but don’t know if is could be an issue for other browsers.

For anyone needing this, I have a pull request in, but since that will probably never get merged, you can point to my branch in your projects: https://github.com/stevenvachon/classList.js
