Issue reported by plt2 via IRC.

Currently, this has RIP.supported which returns true if RIP is
supported by the client, and rip.loadicons(archive) which sends
all the icons (and .RIP files) in the specified archive (either
an Arcive object or a filename) to the remote if they don't
already have them.

If you have a RIP enabled door, a small JS script as a pre-run
command like this:

require("rip.js", "RIP");
rip.loadicons('/sbbs/xtrl/lord/lordicns.zip');

Will automatically send all the icon files in the arcive to the
user if the user doesn't already have them.  For SyncTERM as of
this commit, they will be placed in the cache directory for that
BBS (and only be available for that BBS).

On *nix, the cache dir is ~/.syncterm/cache/<bbsname>
On Win32 it's something like:
C:\Users\User\AppData\Local\Microsoft\Windows\INetCache\SyncTERM\cache\<bbsname>

No ideal what it is on macOS.

If the extended description and the normal (short) description are the same,
delete the extended (long) description.

Duplicate archives (e.g. ZIP files) often have the different digest/hash/CRC
values because they have a different ZIP comment or the files were archived
in a different order or used different compression schemes. You can now detect
(and delete) these duplicates.

moved postit.js to its rightful home in the xtrn folder. anyone using this script likely already has it there anyway. if not, data files should be moved for anyone updating their local script. no file changes have been made.

Made some other cosmetic improvements/fixes.

This appears to be enough to make hatchit.js work again and file
listings in webv4 (not sure beyond that).

This file is now just an unnecessary shim and should go away when
the consumers (hatchit and webv4) no longer need it.

I did not "port" support for the file properties:
- base
- ext
- datoffset
- opencount
- misc
- altpath

They don't appear to be needed.

dir is not a property of lib_list[], appears to be a typo.

Also, in the "lib" scope commands, j was not defined.

The offline_dir property appears to have been deprecated (no longer
enumerable) years ago, in favor of the dir/dir_list[].is_offline
property, so use that property instead for skipping offline dirs.

Also, make sure the ;upload and other lib/all search commands are
abortable with Ctrl-C.

Upon connecting, a client will be sent a list of who's online on
the local BBS as well as other systems (if you and they are set
up for instant messaging). Updates will be sent for subsequent
events (logon, update, logoff).

Mostly intended for use by local consumers; you probably don't
need to open any ports for this.

Nothing uses this at the moment and you do not need to add it
to your config. Eventually it'll bring interBBS presence and
messaging back to webv4 and probably introduce a fancier textmode
imsg module.

Properly throw an error instead.

but round-up non-zero values to 1K.

Appended very important trailing linefeed.

The biggest difference is that you can combine all files from multiple dirs
into a single sorted list and you can sort on any property (field) value.

The byte/credit format is very customizeable, the output format is completely
customizeable.

By default, just the filenames are output, but either use '-ext' or one or
more '-v' values to add more fields. Use -p=list to specify a comma-separated
list of properties to print.

Instead, return the fractional size in KB's with 2 digits of precision.

Fixed up some of the variable names.

Returns a floating-point formatted size estimate more in-line with my
preference (e.g. 17.0G instead of 17,000M).

Fix bseen calculation and saving
Only save seen data after all repsonses have been sent
Stop processing when the socket has been closed

Can find duplicate files in your file bases by name and/or hash sum - fast!
Can output simple text or JSON format.
Run 'jsexec dupefind' to search just for duplicate files by hash (SHA-1)
or run 'jsexec dupefind -help' for the various usage options.
