$.param does not support array object.

I use jQuery.Hive.Pollen version: 0.1.91 with Web Worker.

it not work when I send POST request

```
$.ajax.get({
    url: 'xhr_echo_request_json.php',
    data: $.param({ a: { b: 1, c: 2 }, d: [ 3, 4, { e: 5 } ] }),
    success: function(data) {exactly the object sent" );
    }
  });
```
