for the json-service.ini "dir" key. The code that parses that value is not
very tolerant of the absence of a trailing slash.

Add CSI I support.
Fix CSI SP d support.

Loadable Modules for these (nodelist and privatemsg) configured by default
in SCFG->Sysstem->Loadable Modules.
Disable FIDOIN and FIDOOUT timed events by default.
Disable NEWSLINK and LISTSRVR timed events by default.
Added ftn-setup.js and xtrn-setup.js to the Operator xtrn menu.

Added "-export" for F. Krueger (2:333/808.1) which exports every message from
the specified message base into a separate text file (in the sbbs/temp dir).
e.g. "jsexec <msgbase-code> -export"
Uses RFC-822 style header syntax. No dot-stuffing. Strips Ctrl-A codes. Uses
CRLF-terminated lines. All these things could be configurable with options
easily enough if someone wants different behavior.

in adjustuserrec() - as reported by Nelgin, the finder and reporter of bugs.
32-bit fields were protected, but not 16-bit fields, so they could/would
"wrap around" (e.g. after exceed 65535).
I did not add protection for 8-bit integer wrap as there's only one (leech) and
that's not relevant/used these days.

Apparently, SyncTERM is doing tabs differently than XTerm, and there's some
