Listing copyright info in each file

…is just silly.

I found a way to list it for each line!

public class HelloWorld {                  // © 2015-2016, Stijn de Witt
  public static void main(String... args){ // © 2015-2016, Stijn de Witt
    System.out.println("Hello, World!");   // © 2015-2017, Stijn de Witt
  }                                        // © 2015-2016, Stijn de Witt
}                                          // © 2015-2016, Stijn de Witt

(I changed the program twice, but due to using the clearly inferior method of tracking copyright per file, I’m not sure which lines changed in 2016)
