message numbers should be printed differently for each context, so added a
'reading' boolean argument (defaults to true) to indicate it was called from
readmsgs() and to use the index offset (+1) as the printed msg number in that
case.

The (O)perator (D)elete message (range) command will now skip permanent msgs.
Fixed bug with (L)ist msgs command while in (S)earch for Your Messages mode
(the msg numbers listed did not match the msg numbers used by the Read prompt).

Warn if DOVE-Net subs are configured to disallow voting or they are not
configured for QWK networking.

full path (sans file suffix/extension), it would use that path for the menu
file to be displayed.

twitlist.cfg) - this allows adding a filter of say " *" which will filter
out names (e.g. mail "Fromt" names) beginning with a space character.

sub-board of the "Reading" prompt. This allows a sysop or sub-board
operator to quickly delete a range of messages from a message base. e.g. for
easier clean-up of msg-net hiccups or intentional spamming of subs.

(e.g. as the result of a search for text or messages to you).

HEX_DIGITS() and DEC_DIGITS()

better invalid destination address detection.

address (if valid), for use with sbbsimsg.js.
Added 'include_self' parameter to read_sys_list() to control whether or not
the local bbs is excluded from the returned list (for chksetup.js use).

Some objectification of the edit_area() and edit_globals() functions, these
2 functions really should be merged since they appear to be mostly just a
copy/paste of one another. :-(

(tickit.ini) rather than the internal code.
Thanks for the report, Ragnarok.

ctrl/modopts.ini file. Used by scripts performing frequent node activity /
user presence actions.
Thanks Ragnark for pointing out that I had forgot to add this file to CVS.

(in bbs.mods).

Implemented the "active" special sort order.
Added support to the remove_dupes() method for the verbose option.

Added the 'active' command (show last active date for all entries)
The 'dedupe' command now supports the -v (verbose) option.

specific BBS entry on this page, e.g. http://synchro.net/sbbslist.html#your_bbs

- uses the sbbslist_lib.remove_inactive() method
- uses the (new) max_inactivity (days) value from modopts.ini [sbbslist]
  (default: 180 days)
- supports the -v (verbose) option to display details about entries being
  removed due to inactivity (if desired)

Include service descriptions in the html output, if/when they exist.

- cosmetic fixes (extra CRLFs removed)
- save/use the last 10 telegram recipients (using the getstr() history feature)

(which is updated by sbbsimsg_lib.send_msg() now).

property file (data/user/*.ini), like sbbsimsg.js used to before rev 1.30 when
I moved the send_msg() functionality to this lib but failed to add the property
file update logic. Fixed.

sbbs_t::cmdstr() and cmdstr().

Use case-insensitive check of executable file extension for ".bat".
The obvious "fix" would have been to use strcasestr() instead of strstr(),
but that would leave the unlikely corner case of x.bat.exe producing a
false-positive, for example. Use the proper functions for getting a file
extension and performing a full case-insensitive string compare.

removed unused "var tmp2".
moved Global Options to own sub-menu edit_globals(). makes cleaner menus.
renamed edit_sourceaddress(obj) to select_sourceaddress(obj).
select a source address from system.fido_addr_list instead of typing anything
you wanted in the sourceaddress field.
when in the source address selection list window:
     ESC for no changes to the source address.
     ENTER on first option in list to remove existing source address.
     ENTER on an address to use it for the source address in generated TICs.

save() methods return true (on success) or an error string. No throw()'s.
