... possible loss of data (yeah, yeah, we know)

This code will do nothing if there's no user logged-in or their terminal is
not ANSI or their terminal dimensions (rows and cols) are set to specific
values (not auto-detected). This code does the same thing as calling JS
console.getdimensions(). Since it waits (up to 5 seconds) for a CPR response
from the terminal, this does potentially slow down output, so caveat emptor.

This could be used by a sysop to address issue #529.

DD area choosers: Replaced hardcoded high-ascii single line character with a variable defining it via hex code (for the help screens)

DD area choosers: Replaced hardcoded high-ascii single line character with a variable defining it via hex code (for the help screens)

The recently updated ctrl/sbbs.ini had MaxLoginInactivity = 10M in
the [BBS] section, which was parsed as 10 seconds rather than the
intended 10 minutes. This fixes that issue and also will now store all
of these inactivity values in duration notation. Existing values stored
in seconds will work fine since that is always the assumed/fallback unit
of time in duration keys.

Thanks for the report!

DD area chooser fixes for lightbar mode: Numeric input (for file area chooser) and wording changes on numeric input (for both)

And use putmsg() for strings that may have @-codes (e.g. ELLIPSIS)

The lower of the configured maximum file size (for the FTP server) and
the available disk space minus the configured minimum free disk space
is used as the maximum file size to allow upload. Appended files
are accounted for too.

Disallow uploads when free disk space falls below minimum configured
minimum free disk space.

This fixes issue #535

this insures that inactive dumb (bot) connections will be disconnected even
when using a script (e.g. animated pause prompt) that doesn't time-out.

Also, if the connected node is the last node (for this sbbs instance), divide
the socket inactivity timeout value in half.

These changes (along with sbbs v3.20) should help with DOS (denial-of-service,
not MS-DOS) prevention.

Mainly for Krueger.

- New keys in [BBS] section of sbbs.ini:
  MaxLoginInactivity (default: 10 minutes)
  MaxNewUserInactivity (default: 60 minutes)
  MaxSessionInactivity (default: none/unlimited)
- Each configured external program/door in SCFG can have its own maximum inactivity setting (or else the session max inactivity is applied)
- moved node-specific sec_hangup to system-wide/shared max_getkey_inactivity (configured in SCFG->System->Advanced)
- moved node-specific sec_warn (seconds of inactivity before sending warning) to inactivity_warn (a percentage of elapsed max inactivity before sending warning), also configured in SCFG->System->Advanced and used for both socket and getkey inactivity detection
- Renamed JS console.inactivity_hangup to console.max_getkey_inactivity (old name remains as alias)
- Renamed JS console.timeout to console.last_getkey_activity (old name remains as alias)
- Removed JS console.inactivity_warning
- Added JS console.max_socket_inactivity (current input_thread inactivity threshold)
- New text.dat string: InactivityAlert (just contains 3 ^G/BELLs by default) used for non-visual inactive-user warning

The MaxLoginInactivity setting in particular solves the problem of custom scripts (e.g. animated pause prompts) that just poll indefinitely for user input and never time-out  - these will no longer cause nodes to be tied-up with inactive/bot users at login.

You may ask yourself, how did I get here? No, you may ask yourself: why configure these socket inactivity max values in sbbs.ini? The reason is consistency: sbbs.ini is where the MaxInactivity is configured for all the other TCP servers and services.

This fixes issue #534 for Krueger in #synchronet

Instead of copy/pasta. No change in function,.

... to make property names more consistent (e.g. with bbs.last_node).
The old names (without the underscores) are still usable but won't appear
in JSDOCS (i.e. jsobjs.html).

This allows scripts (e.g. login.js) to have custom behavior (e.g. shortening
the maximum inactivity timeout) based on how close the current node is to the
configured last node number. There may be other uses too, but for the vast
majority of Synchronet systems, first_node will always be 1 and last_node the
same as system.nodes/lastnode. Ugh, inconsistent naming. :-(

Added a new configurable text string: scanningMessageText

Add some missing descriptions, fix the order of others.

Mainly capitalization, but some typos and added details. 

This mimics default.src very closely, even the curious clear-screens before
the menu displays only when in non-expert mode (?).

I'll likely be using this to recreate some other command shells.

There's a couple of RIP-specific calls to getlines in default.src that I did
not port over (yet).

This commit fixes issue #526 for Nelgin (and any other JavaScript devs).

Note: this file supercedes default.bin, so beware if you have customized
default.src (and built your own custom default.bin), you'll want to move
those to your mods directory to continue to use them.

Another nail in Baja's coffin.

Use rmfiles() to recursively clean the temp dir, if available.

Don't count sub-directories (if somehow created) as files.

Clean the temp dir when exiting this module too.

number rmfiles(directory, spec=*, keep=0)

Removes files and sub-directories, recursively. Use with caution!

sbbs_t::pause() and JS console.pause()...
now excepts an optional set_abort argument (default is true) which controls whether this method will set the global console-output aborted flag (sys_status&SS_ABORT in C++, console.aborted in JS) when the user hits the Quit or No key at the pause prompt.

This method now returns a bool: false if the user entered No, Quit, or Ctrl-C  at the pause prompt.

Nothing makes use of either of these new pause() features yet, but its generally better to not set/rely on global state wherever possible.

For archives with directories, the first call to extract_files_from_archive() from extract_diz() would create sub-directories in the target (temp) directory, but no files within them.

To correctly solve the original problem identified in commit 79a302f4, introduce/use a new 'recurse' argument to extract_files_from_archive() which means to recursively apply the file_list filter (if specified). Always pass 'with_path' argument as false to prevent sub-dir creation.

The JS Archive.extract() method now excepts an additional boolean argument (recurse) following the file list arguments, default is false.

Remove extra whitespace in Archive JSDOC method descriptions to be consistent with other object/class docs.

The connected TCP port detection method only worked for IPv4, so automatically
detecting a CBM/PETSCII connection over IPv6 didn't work. Thanks to Deuce's
xp_sockaddr and helper functions, this was an easy change.
