New Array serializer and changes to existing Json serializer

[ashmckenzie]

Hi,

I had a requirement to $User->to_array() and $User->attributes() wasn't appropriate in the particular scenario because I wanted to exclude the password attribute and I didn't want to override attributes(), so I override to_array() in User like so: -

class User extends Model

    public function to_array() {

      $options = array(
        'except' => array('password')
      );

      return parent::to_array($options);
    }
}

As the Json and Array serialization code is mostly the same, I made the Json serializer extend the Array serializer. Not sure if that's the best approach, but it made the code more DRY.
