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) changed the buffer size
-in such a way that gets() should be safe (theoretically) as it comes from the
-command line (though it can also read input from stdin after starting the
-program). Ideally `fgets()` would be used but this is a more problematic.
-Previously it had a buffer size of 256 which could easily overflow. In this
-entry `gets()` is used in a more complicated way:  first `m` is set to `*++p` in
-a for loop where `p` is argv. Later `m` is set to point to `h` which was of size
-\256. `gets()` is called as `m = gets(m)`) but trying to change it to use
-fgets() proved more a problem. Since the input must come from the command line
-Cody changed the buffer size to `ARG_MAX+1` which should be enough (again
-theoretically) especially since the command expects redirecting a dictionary
-file as part of the command line. This also makes it possible for longer strings
-to be read (in case the `gets()` was not used in a loop). Thank you Cody for
-your assistance!
