Small change in token parser. #105

I'm new to haskell and following this article/tutorial/book. It's very nice thanks for making it! In my version, adding this change makes sense to me and allows expressions like 4 * 12 where the current version only allows 4* 12 and 4*12 which I find a little strange.
