prevents crash in msgbase.get*() methods when passing NaN.
Use sbbs/temp/event# for default event thread temp dir.

loadmail() change which had a trickle-up effect to the higher level functions
that use loadmail().

change.

Created msgbase.cfg.index (as 'undefined').

record number rather than the header byte offset, to be consistent with other
uses of message "offset" in this class.

Created file_area.dir[].lib_name property.

used to further debug failures when MsgBase.error may contain an empty string.

implicitly "root" the property before populating the array. Without this fix,
a GC could free the array while it's being populated.

the include directory to get the new include/mozilla/nspr header files
(or js_internal.c will fail to compile)!
savemsg() now uses smb_addmsg() for most of it's functionality.
savemsg() now accepts an optional client_t* argument, if non-NULL will
automatically call msg_client_hfields().
MsgBase.save_msg() method now accepts an optional client object argument to
automatically set the security log header fields (sender IP addres, hostname,
protocol, and port).

Using new smb macro: smb_hfield_bin() for storing net and agent types.

to/from/replyto_net_addr in input_msg_header() and save_msg() methods.

and net_addr() to smb_netaddr().

call smb_freemsgdat/dfields *after* logging smb.last_error.

smb_getmsgidx/hdr_by_msgid/ftnid() for fast auto-thread linkage.

and aliases for backward compatibility with older source and script files.

automatically convert to a string (even arrays of objects).

msg header property values.

expand_fields (default: true), call with this argument set to false to not
create header fields that do not exist in the SMB version of the msg header.
This is required if the script is going to later re-write the header (with
put_msg_header) and avoid a failed write due to an illegal hdr size increase.

to support >30-bit integers (e.g. current time_t values).

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.
