Running Ardent out of Laravel

The simplest usage (the only one?) for this would be having this snippet somewhere in the bootstrap/config files of your project:

```php
\LaravelBook\Ardent\Ardent::configureAsExternal('en', [
	'driver'    => 'mysql',
	'host'      => 'localhost',
	'port'      => '3306',
	'database'  => 'db',
	'username'  => 'root',
	'password'  => 'mypass',
	'charset'   => 'utf8',
	'collation' => 'utf8_unicode_ci'
]);
```

In my case, I'm using [Restler](http://luracast.com/products/restler/) and needing an external AR library. Hiding the Laravel boilerplate configuration is cool for external usage of libraries like Ardent.
