Allow upload of avatar, use avatar_lib import method after file received.

(to enable avatar usage).

Removed M (minute bank) from menu (key still works however).

default import/export sub-board (default to 'syncdata')
export_freq (default: 7 days)

The user avatars export frequency is now controlled and
user avatars should not be exported unless they've been
recently created or updated or the configured frequency
has elapsed.

There's currently no export frequency control for
collections (ever time you export a .bin file, it'll be exported to
the msg base)

a length property (normally).
Change the command-line usage: one command per invocation, but multiple
files possible (e.g. with "export" and "verify" commands).
You don't need the '-file' or '-users' arguments anymore.

doesn't exist, avatar_lib.read_localuser
may return false instead of null. Just
do a loose falsey test.

Turn node messages off
Restore bbs.sys_status and console attr on exit

Browse local (and qnet-imported) avatar
collections and select one to use as
your own.
This is incomplete. Upcoming features:
- Download your avatar

SBBS. I'm not sure why this works fine from JSexec without this change.
Weird.

custom msghdr.asc and want to continue to use it (with avatars). Just add
@exec:showmsgavatar@ (uppercase) below your custom header in msghdr.asc.

Don't load asc2htmlterm.js unless the user is actually using htmlterm.

(mainly for human consumption).
Added remove, enable, and disable commands.

- enable_localuser() - can be used to disable avatar and re-enable
  (without deleting it).
- remove localuser() - to remove an avatar record completely.

Modified methods:
- draw() and show() now ignore disabled avatars.

list. This allows blank/empty comments to be included in the array
easily shorten the number of comments (if there were some already).

(e.g. when JSON.stringifying).
Removed obj.fontname. We don't use it and it's just a copy of tinfos.

least) - where it saves comments (Sauce "Notes") as a single \n-terminated
comment (limited to 64 chars) rather than an array of 64-char comments.
This doesn't completely fix the problem because PD still barfs when the
total comment length is > 64 chars, but it helps. And we don't want
line-feeds in our comments (e.g. avatar descriptions) anyway!

records on .bin files. Will need a little tweaking for .ans files.

to verify an avatar .bin file) - '.' matches any char except line-endings
and 0x0D and 0x0A are valid attribute values in a bin file. Oops.

Fix typo in import_netuser_list().

background color is set and the next line (e.g. a blank line) causes a
scroll (thus filling with the background attr).

JavaScript doesn't support the \a (alert) escape char apparently.

reuirements (e.g. no chars that'll cause problems, no blink attribute)
before importing or exporting.
Added "verify" command to verify .bin files meet the avatar requirements
(e.g. "jsexec avatars verify -file=/path/to/some.bin")

a JS Date() object.

Have utf8_ascii.js simply replace any returned character greater than 0x7f
with a question mark in the replacement function.

(e.g. areaname -> areatag) for consistency and clarity.

Rastus:
file_to_netmail() assumed the file pointer was at the end of the file.
This was not the case with the areamgr.hlp file (just opened, not read or
seeked).
Also, added some more error logging in case of file_to_netmail() failure.

avatar size) before copying to text/avatars.
Use '-file=<filename>', rather than -f.
Export/share an avatar library like this:
  jsexec avatars export=syncdata -file=../text/avatars/custom.bin
Export user's avatars like this:
  jsexec avatars export=syncdata -users
Import avatars (users and shared libraries), like this:
  jsexec avatars import=syncdata
(replace syncdata with the correct code for the syncdata sub)

1) Only call crpytFlushData() if there *is* data.
2) Only call cryptFlushData() once per call to do_CryptFlush()
3) If cryptPushData() does a short write, flush immediately, regardless of
   the preferences
4) Pass the whole private data pointer to do_CryptFlush() so it can only
   call cryptFlushData() if there's unflushed data
5) Extend the private data structure to track unflushed data

treat NULs as white-space.

1) Accept (and ignore) empty lines from remote
2) Explicitly call the garbage collector to prevent memory hoarding
3) If we fail to fetch a header, make up a dummy one
