Add PsuedoTranslation helper

Here is the example usage of the helper:

```js
app.config(['$translateProvider', 'PsuedoTranslation', function ($translateProvider, PsuedoTranslation) {
    // add translation tables
    $translateProvider.translations('en', translationsEN);
    $translateProvider.translations('xx', PsuedoTranslation(translationsEN, false));
    $translateProvider.translations('xl', PsuedoTranslation(translationsEN, true));
    $translateProvider.preferredLanguage('en');
}]);
```

English isn't too interesting

Psuedo Language (without inflation, called 'xx' in sample)

I think this can be evolved a fair bit (like change the function signature for the second parameter to be an object with various settings).
