Title: Added the ability to override the default "class" virtualAttribute.

You should be able to set the virtualAttribute to something different by passing in the options with it defined. It wraps whatever you pass in with "ko ...:".

```javascript
// you can now do this

var bindings = { ... };

ko.bindingProvider.instance = new ko.classBindingProvider(bindings, {
"attribute": "data-ext-bind",
"virtualAttribute": "ext-bind"
});
```
