We should probably move a few pieces to the config:

- the expiration
- the name of the cookie

See how those values are configged for other cookies in https://github.com/misterbisson/bstat/blob/master/components/class-bstat.php#L149 . It might look something like:

```php
'test_cookie' => (object) array(
	'name' => 'test',
	'duration' => 2592000, // 30 days in seconds
),
```

Those values could then be [localized onto the page](https://github.com/misterbisson/bstat/blob/master/components/class-bstat.php#L272).
