Subject: model: Implement Stringer interface for Recipe

This allows to print a recipe with a fmt.Printf() call more easily:

	fmt.Printf("%s\n", recipe)

This is also used for better error output in unit tests with t.Fatalf().

The Stringer interface is implemented with the JSON package because an
indented version of a recipe is a useful string representation.
