Fix crash in 1991/westley stopping it from working

The problem was that the read only char*z[] was being written to. This
caused a crash which prevented the delightful program from working. The
fix was to change it to 'char z[][100]'. But why not a smaller number
when the longest string is < 100? Because a smaller number caused
strange output and it was easier to do than find the right value: 100 is
that big and it works well so why bother finding the smallest value? No
other reason behind it.

Fixed the shell script too so that it actually works okay (related to
'.' not being in the path in modern systems).

Updated README.md: moved the ttt.sh related things to new try section
and gave an example run (a losing example, challenging users to cause a
draw or better yet win as well as asking them to test something about
the game).

Added a fun parody to the README.md too. Check it out!

+[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) fixed a segfault in
+this program which prevented it from working. The problem was the read-only
+char array `char *z[]` was being written to. The fix was to change it to `char
+z[][100]` in two spots (see if you can determine why two places, not one!). Why
+100 when the longest string is < 100? Because a shorter value caused strange
+output and it's easier to just choose a larger value that works without having
+to find the correct value. Thank you Cody for your assistance!

+## Judges' remarks:
+
+Can you figure out why the board looks different than the
+[westley.c](westley.c)?
+
+What happens if you make a move already made?
+
+Now go try and draw or better yet win!
+Why is win better than draw? Because everyone knows how to draw:
+
+> Professor Falken: Did you ever play tic-tac-toe?
+> Jennifer Mack: Yeah. Of course.
+> Falken: But you don't any more.
+> Jennifer: No.
+> Falken: Why?
+> Jennifer: Because it's a boring game. It's always a tie.
+> Falken: Exactly. There's no way to win. The game itself is pointless. But back
+at the [International Obfuscated C Code Contest judges'
+room](https://www.ioccc.org/https://www.ioccc.org/judges.html) they believe that
+you can win tic-tac-toe, that there can be acceptable draws.
+
 Try not to cheat, the computer has not learned how to catch you doing it.
