move fix thanks a file, update top level html links, rename CONTRIBUTING.md

The fix thank you's have been moved from `README.md` to
`thanks-for-fixes.md`.

**WARNING**: Some mistakes may have been made in doing this.
We presume later changes by others will correct any issues.

The `CONTRIBUTING.md` was renamed `how-to-enter.md`.

A 3rd line of links was added to top level html such as
`contact.html`, `index.html`, `judges.html`, `winners.html`,
and `years.html`.

Improved blank line use in a number (but not all) `README.md` files.

-[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) fixed this for clang by
-changing the third and fourth arg of main() to be ints inside main(); clang
-requires args 2 - 4 to be `char **`. He also fixed it so that the program would
-not segfault if not enough args were specified. He did the same for the
