Title: fix Helpers::DateHelper with :use_hidden - hide separators

Hi,
I've fixed DateHelper. It was rendering separators with :use_hidden => true.

```ruby
<%= f.select_datetime :created_at, :use_hidden => true %>
```

Produced:

```html

—
:
```

Now separators are not shown if `@options[:use_hidden] == true`.
