Remind reader to add newRecipe() function to the RecipesController

Hello!

First: thank you so much for the excellent tutorial!

Now the issue: I think it should be mentioned in the section 4.3 (crud_recipe.md) that the reader has to add the newRecipe() function to the RecipesController (it's got called by click on the New Recipe... button).

$scope.newRecipe = -> $location.path("/recipes/new")

Nice catch! Should be updated now. Thanks!
