Title: Return the raw value if the option is an array

Mongo accepts an array when using sort to allow you to sort by preference, for example

```Person.order_by(:first_name, ['Dan', 'Rob'])```

I know i will need to write tests etc however putting pull request up to get people's opinions, it's a feature i need and wondered why it wasn't allowed in the gem as it works fine.
