Updates and additions to 1989/jar.2

Add a hexa-layered chocolate fudge cake :-) (see below)

Added try.me.sh script which will take a list of files (if no arg
specified it has a default of files added, as described below) and feed
each one to jar.2.

The lisp files added are: fib.lisp from Yusuke Endoh; try.me.txt from
the author; and chocolate_cake.lisp from me. The cake one uses '(quote
...)' that the program supports but the other files do not and plus who
can't use a bit (or lot :-) ) of chocolate cake?

Made the entry look slightly more like the original by adding back the
macros that can't be used but still are part of the entry (#defines for
define and include).
