fix and improve links within the web site

Entry source is now prog.c for IOCCC years 2014 thru 2020,
or is now dirname.c IOCCC years 1984 thru 2013.

To achieve this state, we renamed the following:

renamed:    2004/hibachi/src/hibachi.c -> 2004/hibachi/hibachi.c
renamed:    2012/omoikane/nyaruko.alt.c -> 2012/omoikane/omoikane.alt.c
renamed:    2012/omoikane/nyaruko.alt2.c -> 2012/omoikane/omoikane.alt2.c
renamed:    2012/omoikane/nyaruko.c -> 2012/omoikane/omoikane.c
renamed:    2012/omoikane/nyaruko.orig.c -> 2012/omoikane/omoikane.orig.c

Modified `bin/subst.entry-index.sh` to add to entry `index.html` file,
links to the `Makefile` and the _C code_ to the top navigation bar.
Changed `bin/subst.entry-index.sh` VERSION from "1.2.2 2024-02-25"
to "1.3 2024-03-02".

Moved printing the Inventory link in the top navigation bar
from `bin/subst.entry-navbar.awk` to `bin/subst.entry-index.sh`.
Changed `bin/subst.entry-navbar.awk` VERSION from "1.0.1 2024-02-23"
to "1.1 2024-03-02".

Moved printing the Inventory link in the top navigation bar
from `bin/subst.year-navbar.awk` to `bin/subst.year-index.sh`.
Changed `bin/subst.year-index.sh` VERSION from "1.0 2024-02-11"
to "1.1 2024-03-02".
Changed `bin/subst.year-navbar.awk` VERSION from "1.0 2024-02-11"
to "1.1 2024-03-02".

Added location names (both default and common) to `author.html`.
Changed `tmp/gen_author_json.sh` VERSION from "1.0 2023-06-06"
to "1.1 2024-03-04".

Added location names (both default and common) to `author.html`.
Changed `bin/gen-authors.sh` VERSION from "1.2 2024-03-09"
to "1.3 2024-03-04".

The manifest and the resulting `.entry.json` files have been changed
for `2004/hibachi` and `2012/omoikane`.

The Makefiles for  `2004/hibachi` and `2012/omoikane` copy the
source file into the "previously used location".  The `make clobber`
rule removes the copied source.  The `.gitignore` files have been
updated accordingly.

Improved how the concept of IOCCC terms _entry_, _author_ and _submission_ are
used in markdown files.

Links to markdown files (files ending in .md) within the repo were
changed to link to HTML files (files ending in .html).  Special cases
where `README.md` became `index.html` were modified accordingly.

Fixed URL for `bugs.html` in Makefile comments.

Fixed name of `bin/sgi.sh` referenced in comments in `.gitignore` files.

Links to locations within the repo are now relative.  For example a
link to `/contact.html` may become `../contact.html' or '../../contact.html`
depending on the directory level of the markdown file.

Nearly all links with absolute URLs under _https://www.ioccc.org_
or `https://ioccc-src.github.io/temp-test-ioccc_ have been changed to
relative paths within the repo.  Some exceptions to this (such as
referring to a GitHub repo) were preserved.

Fixed a number of inside `faq.md` and `bugs.md`.

Added HTML name tags (in the form of an _entry_id_) for each entry
referenced in `bugs.md`.  Fixed links from outside of `bugs.html`
into `bugs.html` accordingly.

Where FAQ entries are referenced, a named tag is used so that if a
FAQ is ever renumbered, links outside of `faq.html` will still work.

Changed the _inventory_order_ of a compressed tarball from _300_
to _100000_.  While this may have been done for the manifest,
this changed had not yet been propagated into the `.entry.json` files.

Links to web sites that were in the for <URL> are now [URL](URL).

Performed `name www` to process all of the above.

Improved format of `authors.html`.  Full names are now bold.
Location codes are now links back into `location.html` and
location names (both default and common) are now italics.
Added _author_handle_ each author.

Changed `bin/gen-authors.sh` VERSION from "1.1 2024-02-25"
to "1.2 2024-03-09".

Improved format of `location.html` as location codes are now bold,
author counts in a given location are now bold, and location names
(both default and common) are now italics.

Changed `bin/gen-location.sh` VERSION from "1.0.1 2024-02-23"
to "1.1 2024-03-04".

Added italic location name after location code in entry
`index.html` files.

Changed `bin/output-index-author.sh` VERSION from "1.4.1 2024-02-23"
to "1.5 2024-03-04".

Added _Location of authors_ to the sidebar as a link to `location.html`.

TODO: While nearly all of the above mentioned changes are likely correct,
      they likely introduced a few errors that need correcting.
