BB10 : Globalization

I tried the example below:

```
<!DOCTYPE HTML>
<html>
  <head>
    <title>getLocaleName Example</title>
    <script type="text/javascript" charset="utf-8" src="cordova-2.9.0.js"></script>
    <script type="text/javascript" charset="utf-8">

    function checkLocale() {
      navigator.globalization.getLocaleName(
        function (locale) {alert('locale: ' + locale.value + '\n');},
        function () {alert('Error getting locale\n');}
      );
    }
    </script>
  </head>
  <body>
    <button onclick="checkLocale()">Click for locale</button>
  </body>
</html>
```

It always enter in the error callback.
