Updated brace style.
printfile_fp() no longer reads/displays in 8K chunks, fixes problem with
pauseon/off @-codes in large files.

Better file length and read error checking in printfile() and printtail().

Using <file>.<increment>.<ext> for generating unique filenames instead of
<file>.<article>.<ext>.
Fixed bug (null keyword error) when parsing .cfg file (truncsp will convert
null object to string).
No longer saves incomplete attachments as separate file (imports entire
encoded message in message base for binarydecoder.js to chew on later).

Supports smblib 2.22, which can return static to/from/subj convenience pointers
(on corrupted message headers).
Changed calculation of message header size (in bytes) - no looping.

Changed mime blurb.

required header fields (to/from/subj) is missing. Instead, it just points the
convenience pointer(s) for the missing field(s) to a static null string.
Increased version to 2.22.

spammer technique involves embedding a carriage return character in the
MAIL FROM address.

Fixed is_operator property (was always true).
Created is_download_free() function which checks all the various criteria that
can make a download free for a particular user from a particular file area,
with support for per-directory exemption ARS (finally).

can make a download free for a particular user from a particular file area,
with support for per-directory exemption ARS (finally).

local logging and remote printing of the same string easy:
writeln(log("some string"));

Now appends attachment MD5 to MD5 history file when file is saved.
