Title: allow specification of raw query string

this is useful in cases where there are hidden form fields you need to grab via something like

```
var form_data = this.evaluate(function() {
return jQuery('form').serialize();
});
var base64contents = this.base64encode(form_url, 'POST', form_data);
```
