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 so it would
-compile and work with modern compilers. The problem was that `srand()` returns
-void but it was used in a `||` expression. Thus the comma operator was needed.
-Cody also changed the entry to use `fgets()` instead of `gets()` to make it safe
-for lines greater than 231 in length and to prevent a warning at linking or at
-runtime, the latter of which can be interspersed with output of the program.
-Note that this now prints a newline after the output but this seems like a
-worthy compromise for making it safer (fixing it is more problematic than it is
-worth). In macOS another line of output would be shown anyway namely the warning
-that it uses gets(). A subtlety about this fix: if a line is greater than 231 in
-length if the program chooses that line it might print the first 231 characters
-or it might print (up to) the next 231 characters and so on. Thank you Cody for
-your assistance!

-[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) fixed a bug on systems
-where `EOF != -1`. The problem is that `getc()` and the related functions do not
-return `-1` on EOF or error but rather `EOF`. However `EOF` is not required to be
-`-1` but merely an int < 0 and this program assumed that `getc()` will return
-`-1` on EOF or error, not `EOF`. On systems where `EOF != -1` it could result in
-an infinite loop (for the same reason one should not use `EOF` for the `getopt()`
-functions as they return `-1` when all options are parsed (for details on the
-definition of `EOF` see `7.21 Input/output<stdio.h>` subsection 1 of the
-standard)). An interesting problem occurred where changing the `-1` to `EOF`
-caused both `warning: illegal character encoding in string literal` and `error:
-source file is not valid UTF-8`. But since `EOF` is simply an int < 0 and making
-the loop condition check that the return value is >= 0 does not cause a
-compilation error and it functions correctly it will address the systems where
-`EOF != -1` just as if it checked for `!= EOF`. Thank you Cody for your
-assistance!
