newly added SCFG->System->Loadable Modules: List Nodes, Who's Online, and
Private Msg.

- nodelist (default: "nodelist")
- who's online (default: "nodelist -active")
- private message (default: "privatemsg")

This allows the nodelist and private message modules to be "installed" without
over-riding global hot key events (SCFG->External Programs->Global Hot Key
Events), allows the Baja functions NODELIST_ALL, NODELIST_USERS, and
PRIVATE_MESSAGE and JS bbs.list_nodes(), bbs.whos_online(), and
bbs.private_message() methods to use external modules (JS or Baja)
automatically.

The old C++ logic remains for these features if the module's are cleared (set
to a blank string) in SCFG, but at some point, that code will likely be removed.

"Trade Wars", "TradeWars", and "TRADE WARS", so I'll pick the one that looks
right to me. It's also sometimes v.ii, sometimes (v.ii) and sometimes 2.

had CRCRLF line-endings which causes printfile() to not count lines/pause
correctly.

Removed call to word_wrap.

Clear the screen before and pause/invalidate the frame after executing
install-xtrn.js. And the ".js" is required by js.exec().

(This was a holdover from the long and intensive 15+ minute development
period this script went through.)

Untested. May destroy your BBS, may set off a chain reaction that
destroys the entire planet. Probably harmless.

anything that doesn't print is "fine".

descriptions in socket error messages in a cross-platform
(i.e. WinSock-compatible) manner.

It appears when this module was created it was copied from js_socket.c and
the use of ERROR_VALUE (which is socket-specific on Windows) was not corrected.

Version 1.20: Now uses the DDLightbarMenu class for lightbar mode, and the internal lightbar code has been removed.  Requires the latest dd_lightbar_menu.js in sbbs/exec/load.

Version 1.32: Removed some code that's no longer used.  Also, fixed an issue when changing to another sub-board with the traditional-style (non-lightbar) list where it was slow to list sub-boards.  For the number of messages, it was checking all headers to ignore ones marked as deleted, etc., but that can be fairly slow..  Now it just uses total_msgs for the MessageBase object, which is a lot faster and still gives an idea of how many messages are there.

Some no-pause/screen-clearing stuff in demo().

Support modopts.ini sections: [qnet-ftp] and [qnet-ftp:<hub-id>] to allow
passive FTP (the default) to be disabled and over-ride the local FTP data-port
and network interface (bind host).
