Subject: [PATCH] improve topbar

The icons used to show the menu open (`png/hamburger-icon-open.png`)
and closed (`png/hamburger-icon-closed.png`) have been added.

Changed `inc/topbar.default.html` to use the png icons instead
of a svg file.

A new page `nojs-menu.html` has been added for when
JavaScript is disabled.

Changed `bin/gen-top-html.sh` VERSION from to "1.4.4 2024-04-21"
to "1.4.5 2024-04-23".

Sorted top sections in `inc/md2html.cfg` and added
a section for `nojs-menu.md`.

Fixed `ioccc.css` so that the topbar and related pulldown
menus had the correct background colour.

Ran `make www` to perform the above.

TODO: Detect when JavaScript is disabled and display:

		Please
		Enable
	      JavaScript

      As a link to the new `nojs-menu.html` page.

TODO: Fix a problem on wide screens where some of
      the righthand edge pulldown menus are cutoff.

TODO: Fix the 5 HTML 5 errors introduced by the topbar code.
