Title: Allow the virtualAttribute to be overridden

Since you can already override the default html element attribute, it makes sense to allow overriding the virtualAttribute as well.

```javascript
// you can now do this

var bindings = { ... };

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