Title: Remove direction select control from sort_select form builder

Remove direction select control from sort_select form builder and put it into its own sort_direction
helper method. This allows the two select controls to be passed different html options so that they may be styled more easily. See issue 306. The sort_fields block will now look like:

```erb
<%= f.sort_fields do |s| %>
<%= s.sort_select %>
<%= s.sort_direction %>
<% end %>
```
