MsgBase.save_msg() now supports an optional recipient_list argument (array of
header objects) to send a single message to multiple recipients (e.g. bulkmail).

from_protocol and from_port JS msg header properties (and documented).

for additional tracking information.
Created DLL-exported msg_client_hfields() in postmsg.cpp as a common function
to add these client tracking header fields.

used to trace message origins for security reasons.

the system timezone, which handles the optional automatic toggle of the DST bit
for US-zones in real-time. Previously, the DST flag would only be toggled when
loading configuration files, now it will happen in real-time.

(whenever possible), for documentation purposes (jsdocs.js).

(using JS_ValueToInt32 instead of JSVAL_TO_INT).

smb_hfield_append_str() used for creating and appending ASCIIZ header fields.
These functions handle the string-length calculation automatically.

hfield type specified in string (or UNKNOWN, if not found). Returns parsed
number if string contains a number.
smb_hfieldtype() now returns mixed-case (easier to read) versions of hfield
type names.

group_number, and newsgroup properties are always defined.

New retry_delay property (number of milliseconds between lock/read attempts).

leaving last_error alias for backwards compatibility.

Added more property descriptions (for dynamic JS object model docs).
Fixed a few bugs exposed by jsdocs.js.
Using JS_NewNumberValue for full 32-bit integer support (bitfields mostly).

user.compare_ars method in jsobjs.html.

(faster than retrieving a complete message header).

supports properties: to_org, replyto_org, to_agent, from_agent, and
replyto_agent.
Changed conversion of jsval types in parse_header_objects().
Added documentation for supported header object properties in save_msg
method.

fields (preparing for auto-thread linkage).

The other get/put methods now return null/false correctly if no msg
id/offset/number was specified.

message-IDs.

final header retrieval (rather than two).

by ID rather than by offset or by number (by passing a string instead of a
number variable/value).

parsing the header object parameter, to prevent duplicate header fields from
being saved back to the message base (bug reported by Guardian Angel).

Repeating ASCII header fields (e.g. RFC822HEADER) are accessed with the
hdr.field_list array.

put_msg_header() method now update the index record too (to/from/subj/attr).
