add quick-readme2index.sh, improve all-run.sh and readme2index.sh

Improved `all-run.sh` and `readme2index.sh` so that
certain command line options (e.g., -p, -P, -u, -U ...)
are only passed along to other tools if they are
given on the command line.

all-run.sh VERSION changed from "1.1.1 2024-01-19"
to "1.1.2 2024-01-20",

readme2index.sh VERSION changed from "1.1 2024-01-16"
to "1.1.1 2024-01-20".

Added `quick-readme2index.sh` that only calls
`readme2index.sh` if the `index.html` is not
a non-empty file, or of either `.winner.json`
and/or `README.md` is newer than `index.html`.

Updated all `index.html` files because the
the file contains a comment that includes
the newly modified readme2index.sh VERSION.
