sbbs_t::mnemonics() now supports @-codes immediately following the tilde
(e.g. ~@Yes@) to use the first character of a dynamically-replaced
(e.g. localized/translated) text string as a command key.
Fixed issue in sbbs_t::mnemonics if multiple @-codes were specified in the
string, but no space characters (just noticed this bug while reviewing).

Created: sbbs_t::expand_atcodes() - used by sbbs_t::mnemonics(), exposed in
JS as bbs.expand_atcodes().

bbs.text and system.text now have properties: each text string ID is the
property name and the text index number (1-based) is the property value -
enabling fast text string lookup without load/require text.js

Constified sbbs_t::atcode() and attrstr() - not too painful

Deprecated YNQP text.dat string in favor of (the first character of)
  "Yes" and "No" text strings and new strings: "Quit", and "PasswordChar"

Other text.dat changes: ListKey->List, AllKey->Unused853
More new text.dat strings: Which, Next, Previous, Language, LANG
Deprecate the "AllKey" text string
Create/use sbbs_t::all_key() - first character of "All" text string

New JS console properties that present common (possibly localized) command
keys: yes_key, no_key, quit_key, all_key, list_key, next_key, prev_key

This could use more cleanup (e.g. instances of "MSGERR:") and in the summary
report there are still mentions of "message" after scanning a file base.

for those that want to use cryptic numbers rather than human-readable names.

There are other ways to generate forced-upper case expanded @-codes, if that's
what you want.

Fewer duplicates in text.dat make localization, translation to other languages
easier.

See issue #648 for details.

The uppercase ON and OFF are being deprecated

Fixes issue #648

These were problematic (crash, could corrupt filebases) and unsupported,
so just change the programs to stubs that alert the sysop that they need to
switch to using the JS versions of these utilities immediately.

Only the common/UIFC-type arguments should be passed-on.

This fixes issue #646

It also appeared that the user editor spawning wouldn't work correctly
when arguments were passed to umonitor (missing a space).

e.g. as a logon script "?replace_text es" would replace strings from
ctrl/text.es.ini (for Spanish translations)

This is not really to be used to load ctrl/text.ini since that is support is
built in (in load_cfg.c) and not necessary to be done in JS.

Of course, I'm just guessing using DDG Translate, I don't actually speak
these languages with any fluency, so I could use help from those that do.

These files aren't directly used by anything yet. One could copy or symlink
them to ctrl/text.ini or dynamically load them for certain users (right now,
that'd be done via JS).

Hm.

The TEXT:<x> @-code can now be used with the text.dat string ID rather than
the text.dat string number, if preferred.

For convenience and brevity, ALL text.dat string IDs are now valid @-codes
(case-sensitive). While this functionality is redundant with the TEXT: @-code
now, if there are any conflicts between new/existing @-codes and text.dat
string IDs, the TEXT: @-code can be used to overcome such conflicts.

This should help with localization (to other languages) by using common
single-word replacements (Which, Quit, Next, etc.) in text.dat strings.

The syntax of text.ini is:
<id>: "string"
<id>: "string"

Where <id> is the named identifier of a text.dat string as seen ctrl/text.dat
and string is a literal string value (optionally, in double-quotes). Line
continuations (for long strings) are not supported: you'll just need to put
your string all on one long line (up to 1024 char string).
C-escape characters for control chars and hex-encoded chars are supported.

This should address feature request issue #644

After 90 minutes of waiting, we'll do the same abort wait (and run the event
anyway), but closing the node's socket should be enough to get the node_thread
to terminate and set the node status back to NODE_WFC.

Apparently some sysops like to leave their terminals idling (e.g. running MRC)
and never disconnect and since they're T-exempt, the BBS won't limit their
time online to allow events to run. Exclusive events will wait for all nodes
to become inactive, but give up after 90 minutes of waiting and run the event
anyway and set node status to WFC at the end. If the node was actually still
connected/in-use, this could lead to the (new) critical error messages logged
"!Node X status is WFC, but the node socket (N) and thread are still in use!"
and other chaos (NODE STATUS FIXUP and the like).

This should prevent all that by just abruptly disconnecting the node after
waiting 60 minutes for the sysop to gracefully disconnect. The log message
when this happens:
"!TIRED of waiting for node N to become inactive (status=X), closing socket Y"

Mark them all "UNUSED"

Fixes unnecessary [Hit a key] prompt.

This appears to work around a bug in BRE, FE, and TAL where they don't
recognize the "1" (ANSI supported) unless there is at least one other
character on the line following the decimal digit, resulting in the
unnecessary prompting of the user:
  This game is much more enjoyable with ANSI graphics enabled.
  Do you want ANSI Graphics? (Y/n)

As reported by "ben" in IRC.

Fixes issue #645

Fix-up the require() statements.

Also clear the screen immediately cause it can take a noticable amount
of time to read/parse the file.ini and main.ini files.

When used, replaces built-in user (e.g. terminal) settings menu with a
loadable (e.g. JS) module.

... or else any changes we make aren't saved (we're just modifying this
object in memory).

Fix the heading (user alias is displayed, not name).

Fix the mouse hot-spots.

Fix the "None" default download protocol (requires latest text.js).

Fix the hot-key option (inverted logic).

Don't display the [K] Command Shell option if there's only one available.

I finally reproduced this issue myself on a fresh install on Windows.

We needed explicit file closing here as going out of scope doesn't immediately
finalize (and close) a File object. That may not happen until garbage
collection and thus prevent subsequent re-opens of the same files, so always
close() your files.

init-fidonet.js calls install-binkit.js which uses cfglib.js, so that was
a source of these errors too.
