set them appropriately.

an invalid login for a random (the last read?) user account with a user number
of 0.

This needs testing and validation feedback, ASAP, as it's mere existence in
the exec directory means that it'll usurp qnet-ftp.bin (!) and if it doesn't
work, our precious QWKnets will suffer. :-/

... Another (rather large) nail in Baja's coffin.

configuration data.

Use this throughout lbshell.

The F and L keys now nagivate to the first & last pages, respectfully (unless the calling code has added either of those keys as additional keys to exit the input loop in case the calling code wants to handle those keys for something).  Also, fixed a minor bug in calculating the length of items to print when the scrollbar is enabled but not refreshed on the screen when writing the items.

Track and log the packet-export exceptions (link packets that were *not*
exported-to) and detail those exceptions (number of seen-bys, paths, origin
address, etc.) which were triggered.
This requires latest xpdev/str_list.*

Requires the latest SCFG with the new "-misc=<val>" option.

- auto-increment the next sub position
- save and auto-increment the last conference number

This reduces the task of adding of subs to a QWKnet hub to just a bunch of
jamming on the ENTER key (usually).

<sys_zone>:<sys_net>/0. That's just surprising and undesired behavior.
Leave the old address in place in that case.

command-line (uisng -misc=<value> in addition to -import=<filename>). The
value can be decimal or 0x-prefixed hexadecimal, but you need to know the
property bit-flag value (SUB_* in sbbsdefs.h). For use with init-fidonet.js

why his messages aren't being exported to packets.
Don't increment the per-area-export counter when write_to_pkts() returns false.

JS numbers are double-precision floating points (doubles) and doubles cannot
be converted to unsigned integers uniformly across all architectures (e.g.
specifically on ARM, negative numbers would mostly get converted to 0U).

For a screen update optimization, implemented a way to temporarily restrict which part of the items to draw the next time Draw() is called (and thus when WriteItem() is called for each tiem).  There is a new property in the DDLightbarMenu class, nextDrawOnlyItemSubstr, that can be set to an object with 'start' and 'end' properties specifyign the start and end indexes (1 past the last char index) of the item strings to write in the menu the next time Draw() is called.  Draw() will then set nextDrawOnlyItemSubstr to null when it's done.

Also, `* appears to be the same as `^, you just can't normally use it
because it's the node number variable.

Add comment that when converting to ANSI, `* sets the background colour
as well as the foreground, but it clearly doesn't do that for output.

Fix "CSI ["

yesno() and noyes() methods:
We need to check the argument count before using the second (optional)
argument or else it has some garbage/left-over value from some previous JS
function call. And no, just increasing the argument count in the method table
isn't enough. :-(
Reported by echicken and DaiTengu, thanks!

Still no modkey support though... cioapi doesn't currently support getting
this information.

XTerm.  This is what the FreeBSD console supports as well, so there's a
chance this works in curses mode too.

Curses is the least likely since IIRC, the curses mouse thing is insane.
