Title: Fixed bug in model validation translate

Validation rules like:

```php
'name' => array(
'rule' => array('multiple', array('min' => 1, 'max' => 7)),
'message' => 'The course must meet one day, right?',
),
```
would throw a warning because it would try to translate `array('min' => 1, 'max' => 7)` so I added a check to see if the arg was a string first.
