Title: Add failing test for inheriting enumerized attributes

Enumerized attributes don't get inherited by subclasses.

```ruby
class Foo < ActiveRecord::Base
enumerized :baz, :in => %w[a b]
end

class Bar < Foo

end
```

I think it's because the class instance variable `@enumerized_attributes` isn't inherited by the subclass, so it's `nil`.
