  Automatically detect child sub-directories and make them available as virtual
  directories for users to download from - only useful via FTP currently.
* Implemented Sorting options for Message Groups and File Libraries:
  Sub-boards within groups and directories within library can now be
  automatically sorted based on the sysop's chosen sort field (long name, short
  name, or internal code)
  - Required that sub-boards are now stored/saved in msgs.cnf based on groups
  - Required QWKnet hub sub-board reference dynamic renumbering
* Implemented "Template" toggle option for sub-boards and file directories:
  A sub-board or directory marked as "template" will be used for newly created
  (or imported) subs/dirs for that group/lib. Clone Options via SCFG will now
  use the "template" item as the source of the cloned settings, if available.

- Include Kludge Lines     (Yes)
- Include VOTING.DAT File   (Yes)
- Include HEADERS.DAT File   (Yes)
- Extended (QWKE) Packets    (No)
- Exported Ctrl-A Codes    (Strip)

SBBS/QWKnet nodes now have more control over the REP packet files created
by their systems. If the "uplink" (hub) is complaining about receiving
unsupported files (e.g. VOTING.DAT) or kluge lines (e.g. @TZ), just turn them
off.

Also, Ctrl-A codes may now be retained in QWKnetmail. And the @REPLYTO kludge
line enabled for the first time (!).

mode for a specified message base (mail or sub-board). This logic exists in
many other files and can now be consolidated using this single function.

messages), you can now set the Guest accounts new-msg-scan values. The default
is 0 (no new messages).
Using a value of 0 for this or the New User Days of Messages value results in a
very fast message pointer initialization (no "Loading Message Pointers..."
delay).

Sysop can set the number of days-worth of new messages that new users will
see in their first new-message scan (the default is 0, no new messages).
This does lengthen the amount of time that the first "Loading message pointers"
is displayed (it has to go and open all the message bases), but at least new
users are no longer bombarded with thousands of very old messages when they
answer "Yes" to the "Scan for New Messages" prompt. This setting is in
SCFG->System->New User Values->Days of New Messages. Set it to some really
high number (maximum of 9999) if you want the old behavior.

Optionally, external modules may be executed in place of "built-in" operations
for:
- reading mail (email or netmail)
- scanning posts (searching/scanning/reading a single sub-board)
- scanning sub-boards (all, one, or a group)

Each of these may be configured (in SCFG->System->Loadable Modules)
with command-line options for a total length of up to 63 characters.

Note to module programmers: each module here will be passed additional
command-line arguments to indicate how or why the user operation was invoked.

For the Reading Mail module, the 'which' value (in decimal) and the user-number
is passed (in decimal). Usually the user-number will be the current user logged
in, but not always (e.g. if the user is a sysop and reading other user's mail).
The 'which' values (defined in load/sbbsdefs.js) of MAIL_YOUR, MAIL_SENT,
and MAIL_ALL must be handled (MAIL_ANY won't be used).

For the Scan Posts module, the sub-board number and scan mode (both in decimal)
and the 'find' string (text being searched for) are passed as arguments
(in that order). The scan mode values (defined in sbbsdefs.js) are the same as
those supported by bbs.scan_posts(). All of the values should be supported
and they can be combined (e.g. SCAN_CONST|SCAN_NEW
and SCAN_NEW|SCAN_TOYOU). The 'find' string is only used if the SCAN_FIND mode
bit is set. It is the responsibilty of the module (if configured) to enforce
sub-board read access restrictions.

For the Scan Subs module, the first argument is 1 if "all subs" are being
scanned, 0 otherwise (normally the user is prompted for the breadth of the
scan in this case, but that's up to the module author), and the scan 'mode' is
passed in decimal, in that order. If the SCAN_FIND mode flag is passed in, this
module should prompt the user for the text string to search for. If this module
is not configured, the Scan Posts module will be executed for each sub-board
scanned.

Recursion protection was added, so it is actually possible for the Read Mail
module, for example, to call bbs.read_mail() and it'll work, but why would you?

If any of these user operations are initiated during logon, at the request of
Baja or JavaScript module, or whatever, and if the module is actually
configured (and not already executing to handle the operation), the module
will be executed in-place-of the built-in functionality. Feedback welcome,

also clear the associated counts (sizes) for these arrays, eliminating some
potential crashes while dereferencing these arrays after freeing (e.g. during
shutdown or recycle of sbbs).
