use bin/jval-wrapper.sh instead of direct grep of JSON files

We use the `bin/jval-wrapper.sh` tool to obtain information from JSON
files instead of attempting using a "GROSS HACK" that involved using
`grep(1)` (and friends) as those "GROSS HACK"s assumed that the layout of
the JSON was canonical.  The `bin/jval-wrapper.sh` tool is able to deal
with various layouts of JSON including non-canonical layouts.  Moreover,
by using the `bin/jval-wrapper.sh` tool we greatly reduce the places in
bin tools that contain "GROSS HACK"s.

Improve `-v 1` debug messages for `bin/gen-authors.sh` to give some
level of progress instead of a long pause.  Improve `-v 3` as well.

While the `bin/jval-wrapper.sh` tool is slower, it is also more accurate
in that various non-canonical JSON layouts will not confuse the tool.

Apologies for the slowdown.  Once the `jval(1)` tool is ready, it should
be faster than the `JSONPath.sh` tool that `bin/jval-wrapper.sh` uses now.

Added `-Q` to  `bin/jval-wrapper.sh` tool to perform a quick exit if
`authors.html` is newer than all `author/author_handle.json` files.

Updated the top level `Makefile` by adding `make quick_authors` rule
that will invoke `bin/gen-authors.sh -Q`.  Also changed `make quick_www`
to call `make quick_authors` instead of `make authors`.

Changed `bin/gen-authors.sh` VERSION from "1.10.7 2024-08-05"
to "1.11 2024-08-13".

Make a minor improvement in the usage message for `bin/gen-other-html.sh`.

Performed `make www` to test the above under macOS.

Performed `make quick_www` to test the above under macOS.
