include_location (defaults to true)
New comments at the top documenting the modopts.ini settings available.
Include misc flags (M for msg waiting, P for do-not-disturb) in web user status
active-users.json was excluding node with the POFF (do not disturb) flag set,
thus making the do_not_disturb property kind of moot - fixed.

The active-users.json response now includes a 'prot' (protocol) object, just in
case we want to use that in the future.

Much of the code in these 2 modules was moved/migrated to the new presence_lib
and made more reusable/modular.

(to be consistent with [nodelist]):
- include_age
- include_gender
and they can be separately controlled.
Also fixed a 'use strict' violation I didn't find before with assignment
to an undeclared variable (uname).

- Enabling JavaScript "strict" mode and resolved the resulting errors
  (mostly in Merlin's "findfile" modification)
- Enabled the use of a [fingerservice] section in ctrl/modopts.ini:
  include_age_gender (default is true)
  include_read_name (default is true)
  findfile (default is true)
  bbslist (default is false)
- New optional "?bbslist" query to return the names in the local sbbslist.json
  Also "?bbs:<name>" to return the JSON representation of a specific BBS entry
- Work-around xtrn_area.prog[] bug where array items could be a non-object
  (e.g. just 'true' in this case) if the user (no user in this case) did not
  meet the configured access requirements for the external program in question
  so the action value in the node/active-user reports would say
  "running undefined" - just display the internal code instead of the full
  name if this the xtrn_area.prog[code] is undefined (bug fixed in v3.17c).
- The ?active-users.json response now includes the numeric node 'action'
  value (for possibly localization in the future), the 'xtrn' name, when
  appropriate, and the current node.aux value. These fields are not currently
  used by the client (sbbsimsg*.js), but may in the future, mainly for
  localization/translation or beautification purposes.

in the node status reports.
Skip nodes with the "anonymous" flag set.
Support new special queries (over SYSTAT or Finger):
- stats.json
- active-users.json
... for easier programmatic parsing (e.g. by sbbsimsg[_lib].js)

since activeuserservice.js was just a copy/paste of fingerservice.js to begin
with. Replace the "command" value for the ActiveUser and ActiveUser-UDP
services in ctrl/services.ini with "fingerservice.js -u".
The "?services" request now uses the portdefs.js to go through a list of known
standard TCP service ports.

Fixed uptime display in ?stats request.
Added user number to user details.
Removed site name (redundant) from user details.
