Fix issue #693

... only operates on a single directory currently. But this should be enough
of a proof of concept for echicken to work with for now.

Ideally, this would be a feature of addfiles.js and file-uploading via the
terminal server and FTP servers.

Using MsgBase.get_all_msg_headers() which didn't exist when this module was
originally written.

Also, include "use strict";

Apparently some Gopher clients prepend a slash to all requests

Fix issue #688

From: Carlos Navarro (2:341/234.1)

Messages that use CHRS: LATIN-1 are not displayed properly in newsreaders
(Synchronet's NNTP server renders them with the default charset=IBM437).

This fix may work: edit exec/load/newsutil.js, at line 77 insert

        case "LATIN-1 2":
                charset = "ISO-8859-1";
                break;

If you want to test: ßΘφ≤· ± (accented aeiou, n with tilde)

I'm doing this manually with String.replace() because the "built-in"
strip_ctrl_a() function doesn't expand ^A/ (conditional line-break) as it
would need to.

02:23:11 <DigitalMan> maybe a button/link to expand/collapse all the extended comments? Would make text searching easier

Only change cursor if desc td has div child; exit desc click handler if no extdesc div; only add div child to desc td if extdesc present;

Top-align cell contents; cursor: pointer on description hover; show extended description if any on description click.

Put th row inside a thead as is proper.
Put td rows inside a tbody as is proper.
Close td elements even if not strictly necessary. Good form.
Use a subjectively nicer font.
Use a subjectively more readable date format.
Put some space and border between table elements.
Stripe rows for better visual indicator of separate data.
Make the header row sticky so we always know which column's what.
Add dark mode colors if browser prefers-color-scheme dark.

Asked for a way to expand list of recipients for a specified user

This just generated unnecessary noise in data/user/*.ini files, no harm.

iniSetObject (used by userprops.js) will set undefined properties as blank
keys in the section (oops, I don't recall if this is intentional or not), so
we need to 'delete' the property instead of assigning undefined to it.

Other small typos/fixes.

More detail to debug a false-negative SyncBBS-detection result

This solves the problem of detecting a Synchronet (for OS/2) BBS at
telnet://wyseguybbs.mywire.org:2300

That system responds with some control characters (NULs and ^Cs)
before the initial welcome banner, so just strip those out.

The Baja PRINT function (used in yesnobar.src/noyesbar.src) calls putmsg()
with P_SAVEATR|P_NOABORT. Without P_NOABORT, putmsg() doesn't display anything
if the global console abort (SS_ABORT) flag is set.

So hitting 'N' or Ctrl-C at one yes/no or no/yes prompt would mean any
immediately subsequent yes/no or no/yes prompt would not be displayed.

Now that we have to require('sbbsdefs.js') for the P_NOABORT definition,
this'll run a little slower. :-(

Enable/conform to "use strict" mode.

Why does a function this small need a comment describing its return value in
the first place? <sigh>
