Fix deprecated (as of Rails 3) use of routes => match becomes get

In the Rails 4.0.0.beta using match in routes.rb raises an error.  It was deprecated in Rails 3.

````
You should not use the `match` method in your router without specifying an HTTP method. (RuntimeError)
If you want to expose your action to GET, use `get` in the router:

  Instead of: match "controller#action"
  Do: get "controller#action"
