Front end version 2 work in progress

To wit, regarding the `kitchen_location` view helper, this is "duplicated logic".  Both this view and the other view have shared knowledge, viz., how to format a kitchen location for display.  If you ever decide you want to change how a kitchen location is formatted for display, you'll have to change both of these views along with any other views that use this logic.

On the other hand, if you had abstracted that logic out into its own helper, each view would just call `kitchen_location`.  In this instance, the view would call

```erb
<%= kitchen_location(reservation.kitchen) %>
```
