add next/register.html page, improve bin/gen-status.sh

Added a new `next/register.html` that is required by the mailing list server.
The `next/register.md` still contains a big **XXX - put more data here - XXX**
as a placeholder for information about the mailing list registration process.

Improved the status text for `faq.html`, `next/index.html` and `status.html`
via `faq.md`, `next/README.md` and `status.md`.  We also removed the
excessive links to IOCCC and instead use the term "contest" where applicable.

IMPORTANT CHANGE: Registration be available when the contest is both pending and open.

We made a number of changes to `faq.md`, `next/README.md` in an attempt to
reflect the above.

Changed `bin/gen-status.sh` VERSION from "1.7 2024-09-23"
to "1.8 2024-11-23".

Changed `bin/gen-top-html.sh` VERSION from "1.4.9 2024-08-11"
to "1.4.10 2024-11-23".

Perform `make www` and `make gen_status` to perform the above and test under macOS.

TODO: Change **XXX - put more data here - XXX** in `next/register.md` for information
      about how to join the mailing list.
