Adds controller and action data to each connection.
No need to specify the controller folder.
Enables Sugar.View.Finder to find views when they don't have extension.
Use Map.get/3 in case the key does not exist.
Adds a controller test.
Adds render/1

Now we can avoid specifying the view to render and it will just use the action name to choose which view to render.
