Changes to the Syntax

Well, I tried to be smart and that didn't pan out. I thought using a comma would shave off some characters from pattern definitions because

[ cons X XX, cons Y YY -> .. ]

versus

[ (cons X XX) (cons Y YY) -> .. ]

That is one comma versus four parentheses.

But, as it turns out, the prelude is exactly as large for both alternatives and the standard manner of writing things made the Conway's Game of Life program a tiny bit shorter.

I changed the syntax to the standard manner because people seemed to like that more.
