No attempt has been made to make this play nicely with colspans,
but it does work with wrapped cells.

domain name from sbbsecho.ini), use its value as the domain name in the
lightbar list.
For nodelist_DomainName keys, use the DomainName portion as the domain
name in the lightbar list.
(Don't use the parsed domain name from the nodelist file's first line,
this is unreliable.)

log the filename and error if one occurs.

Replaces 'ftnnv' thing that's been floating around.
Loads any nodelists you've configured in echocfg/sbbsecho.ini.
Has a search feature, let's you send netmail.

You can optionally add this section and any keys to modopts.ini:

[fido_nodelist_browser]
auto_close_domain = true
auto_close_zone = true
auto_close_net = true
nodelist_a = /path/to/some/nodelist
nodelist_b = /path/to/some/other/nodelist

The auto_close settings control whether branches in the lightbar tree are
closed when you open another at the same level.  The defaults are more
memory friendly.

If you have nodelists not known to sbbsecho (or aren't using sbbsecho 3)
you can add them here; the key must begin with 'nodelist_'.  Wildcards
are not supported; you should have some external mechanism copying the
current nodelist to a fixed path & filename.

record in the node.dab - only the node(s) that have the requested user
number.
In sbbs_t::getsmsg() and ::getsmsg(), strip all invalid Ctrl-A attribute
codes (e.g. clear screen, pause, etc.) since short-messages (telegrams)
can come from external sources.

Double the duration to wait for client threads to terminate. Heck, this might
should be an infinite wait since "bad things" happen if the client thread
continues after a cleanup().

actual message number (rather than a 1-based message index offset) by using
#<number>, e.g. "smbutil r#3694" will read the message base starting at
message number 3694, if it exists.

Also documented the [-n] syntax for reading/listing messages less than
n days old.

(e.g. on errors).

separate from the log text and is consistent with the mail server log
output.

alphabetized, so the indexes don't necessarily match the order (of timed
events) in SCFG.

Don't use the word "module".

and the "imsglist" command (ditto) - better dupe detection.

- be used to enter the inter-BBS instant message module with the 'I' command
  (this should make responding to inter-BBS instant messages much easier as
  the recipient can respond from anywhere using Ctrl-P global hotkey).
- be installed using "jsexec privatemsg.js install"

- less verbose startup (don't display every system being pinged)
- store the info for the last sent message and use that or the last
  received message to automatically fill in the recipient of telegrams.

This entire module could still use some re-write. It'd be nice if it
automatically re-pinged all the systems and displayed newly discovered
users or those who have apparently logged-off.

- Fix apparent bug when there was no incoming data.
- Include the sender's avatar if one is found and the sender did not send
  the most recent message to the recipient (don't repeat the avatar
  needlessly).
- Store the information (name, address, etc.) for received imsg's in the
  recipient's property (.ini) file. This makes quickly replying easier.

Note: the receiving messages for a node-number feature should probably just
be removed.

Use strcasestr() for message body/header-field text searches (simplify
the code) - not sure why we needed strip_ctrl(), so removed.

MSG_SUMMARY is currently never populated by anything.
MSG_TAGS is a new (optional) thing.

more than one consecutive space character mid-string.
The returned value is still the non-trimmed string length - perhaps that

Chomp whitespace from bold/italic/underline/monospace text.

a message header.
Added "tags" and "summary" (previously missing) to the property fields
parsed when adding/writing a message header. This parse code is getting
particulary copy/pasta and should be converted to a table-driven loop
reusing the same logic.
