git mv *.hint -> README.md

There is one exception:

    $ find . -name '*.hint' -execdir git mv '{}' README.md \;
    git statufatal: destination exists, source=1992/albert/albert.hint, destination=1992/albert/README.md

Looking at the two files they differ quite a bit so I've not changed it.
I'll bring this up on GitHub.

+Judges' comments:
+
+    If your machine support the X Window System, Version 11:
+	make kivinen
+
+    The type of entertainment depends on number of arguments
+    you have with the program.  :-)
+
+    NOTE: Some systems do not need (or have) -lsocket -lresolv -lnsl.
+	  Such systems should compile using -lX11.
+
+    NOTE: The original winning source kivinen.orig.c assumed that
+	  exit returned a value which cause problems for some
+	  systems where exit returned a void.  The file kivinen.c
+	  avoids this problem.

+    X Entertainment Kit
+
+    This kit includes three games from the early of video games for
+    The X Window System Version 11 Release 5. It should work with
+    earlier releases, though.
+
+
+    Space Invaders
+
+    The classic game of shooting aliens from outer space, trying to
+    exterminate all life on earth. The game ends when the first line
+    of aliens touches the ground, or destroy you. To win the game you
+    must destroy all the aliens. If you evade out from the screen you
+    lose.
+
+        Controls:
+                Button 1 = Move left
+                Button 2 = Fire missile
+                Button 3 = Move right
+
+
+    Breakout
+
+    Break all the bricks with the ball, using your paddle. If you miss
+    the ball the game ends.
+
+        Controls:
+                Button 1 = Move left
+                Button 3 = Move right
+
+
+    Dropout
+
+    Catch all the falling pieces, before they reach the ground. If you
+    miss it, game ends. To win you must catch all 30 pieces.
+
+        Controls:
+                Button 1 = Move left
+                Button 3 = Move right
+
+
+
+    Starting the game
+
+    The type of the game is determined by the number of arguments
+    given to the program.
+
+        no arguments = Space Invaders
+        1 argument   = Breakout
+        2 arguments  = Dropout
+        3 arguments  = double sized Breakout
+        4 arguments  = triple sized Space Invaders
+        5 arguments  = triple sized Breakout
+        6 arguments  = double sized Dropout
+        7 arguments  = quadruple sized Breakout
+        and so on...
+
+
+    Scores
+
+    The exit value of the game is your score. The smaller the score
+    the better it is. The exit value of zero means you have won.
+
+
+    Features
+
+    The game has a cheat system, which can be found after examining the
+    event loop at the end of program. It is not a bug, it's a feature!
