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 both the
-supplementary program and the program itself (both of which segfaulted and once
-that was fixed only the binary was modified; it was not run but according to the
-author's remarks it should be executed). He managed to do this with linux
-but it will not work with macOS (see [bugs.md](/bugs.md) for why this is); _this
-is not a bug, it's a feature_ inherent in what it does!
-
-The following had to be done in order to get this to work:
-
-- `#include <sys/mman.h>` for `mmap()` and `munmap()`.
-- have `main()` call another function which is no longer a recursive function;
-this prevented `main()` from entering an infinite recursive loop.
-
-Without either of these it would crash and prevent modification of the 32-bit
-[ELF](https://en.wikipedia.org/wiki/Executable_and_Linkable_Format) (not elf :-) )
-binary. But again see [bugs.md](/bugs.md) here.
-
-The following change was also made to be more portable, in case the constants
-`PROT_READ` and/or `PROT_WRITE` are not standardised:
-
-Change `3` in the call to `mmap()` to be `PROT_READ|PROT_WRITE`: just in case
-`PROT_READ|PROT_WRITE` does not equal 3 (though it seems to be equal in both
-macOS and linux).
-
-There was one other thing that had to be done though. Since the program used to
-recursively call (infinite recursion, seemingly) `main()` and since that cannot
-be done what had to be done instead is after the new function (`pain()` since it
-was a pain to fix :-) ) returns to first call `munmap()` and `close()` (else one
-would get text file busy error) and then the program can call `execv()` again
-like the function `pain()` (was in `main()`) did but with a slight change. See
-commit `2159caec4677e0f25ad704a74e04c8196fd6c343` for more details.
-
-Notice that the location of the calls to `munmap()` and `close()` followed by
-`execv()` _does matter_!
