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.

-After Landon fixed the entry to compile with clang (but see above and below)
-[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) noticed this does not
-work at all in modern systems. He fixed this to work but he notes that the fix
-to let clang compile it breaks the self-test feature.
-
-The problem that was showing up is that with either optimising or if anything
-but 32-bit (as in `-m32`) was used it would not work (at least in 64-bit
-systems?). The optimising cannot be used still but it now works with both 32-bit
-and 64-bit. The solution has to do with the size difference between `int` and
-`long` so that the `long*E` is now `int*E`. This solves a specific problem for
-linux (32-bit, 64-bit) and macOS (arm64).
-
-But as noted there is another problem with clang: the self-test feature only
-completely works with the original version ([giljade.alt.c](giljade.alt.c)), not
-the one that will compile with clang ([giljade.c](giljade.c)). The alternate
-version, which will not compile with clang, is the only one that passes the
-self-tests. If your compiler does not have the defect that clang has about arg
-types to `main()` see the Alternate code section below at least for the
-self-test feature.

-Thank you Cody for your assistance!
