- "Configure" menus (not working since the IPv6 commit) - both IPv4 and IPv6
   addresses may be specified (comma-separated), or multiple IPv4 addresses!
- Added new "Temp Ban" settings to Properites->Security tab.
- Added context (tab) sensitive "Help" button to Properties page
  (links to section on relevant wiki page).
- Every log window has a new right-click pop-up menu with 2 options:
  1. Copy Selected
  2. Copy All
  Hopefully it's obvious what these menu options do. :-)

- Never ban the server's own address
- Log the login attempt and last name attempted
- Use a compressed version of the HH:MM:SS "time remaining" portion of the log

calling Socket.bind() with an undefined hostname parameter would result in a
getaddrinfo() failure, e.g. on Windows, WSAHOST_NOT_FOUND 11001
The ircd.js passes the value of server.interface_ip_address to socket.bind()
and when run from jsexec, this property is not defined. So you couldn't run the
ircd from jsexec or you'd get "!Error 0 binding socket to TCP port xxx".
Also now setting the socket last_error value upon getaddrinfo() failure so
if there is a failure, the error message won't include the erroneous "Error 0".

underlying send() function is free to send a subset of the bytes, and
occasionally does (especially on non-blocking sockets).  The return value
was true if all bytes were sent or false if not all bytes were sent.

The new behaviour is to return the number of bytes sent or null on failure.

This is mostly compatible with existing code which appears to universally use
if (!sock.send(str))

Cases where it's not compatible are when a zero-length string is sent.  The
handling of errors is slightly different now too... previously, if you
retransmitted on failure, the stream would "stutter" now it will have
"holes".

StrictPacketPasswords (default is "true").
If you want SBBSecho v3 to behave like SBBSecho v2 with regards to packet
passwords for linked-nodes with *no* configured packet password, set this value
to "true" in your sbbsecho.ini file. I don't recommend doing this if you care
about the "security" of your echomail, but some sysops have been bitten by the
strict enforcement of the configured password in SBBSecho v3.

I also fixed some (but not all) of the signed/unsigned value comparison
warnings reported by msvc2013. Hopefully this didn't introduce any stupid bugs.

This has been broken (did not track consecutive failed login attempts from
the same client IP address) since the IPv6 commit of Aug-2015. I only noticed
this wasn't working when I was documenting the "auto-block hackers" feature
on the Wiki and noticed that every failed login (even those from the same IP)
was listed as a separate entry in the "Failed Logins" list (e.g.
sbbsctrl->View->Login Attempts). Ugh.

value (of "SYSOP") for the DefaultRecipient key. If it's blank (nobody)
just leave it blank.

(paraphrased) encountered when performing a echomail rescan for link(s):
When a packet reaches the configured "maximum packet size", finalize the
packet immediately (terminate the packet and close the file) rather than
waiting until the very end of all SBBSecho operations.

was listed in multiple additional echolists, it was possible it would
appear multiple times in the areafix response list.

Returns null if the file is not load()ed or the return value from load()

Recipient using echocfg.

non-zero-length string, will touch/create that file if outgoing data has
been processed.

Intended to allow the mailer to scan as soon as outgoing data is available
rather than having it wait for the next normally scheduled scan.

Note, if using this feature as the *only* way to trigger a scan (not
reccomended), any other sources of outgoing data (such as hatching files,
interBBS doors, etc) will also need to touch this semaphore or they will
not be sent until sbbsecho processes outgoing data.

We can't pass a const char * to FREE_AND_NULL, so remove const qualifier
rather than not use FREE_AND_NULL() here.

Back out echocfg.c changes.

With this option enabled, zone/domain mappings from ctrl/ftn_domains.ini are
used to get the outbound directory name, and the orig/dest domains for type
2.2 packets.

This allows supporting 5D addressing in sbbsecho when zones do no overlap
between domains (the normal case).

longer used by SBBSecho (as of v3) and will just confuse sysops if left here.
If you're still using SBBSecho v2, just set the inbound directory in echocfg
(sbbsecho.cfg file) instead and all will be fine.

no longer uses it (as of v3).

original colors when online help is exited. For 80x25 consoles, the user
probably won't notice any change since the online help window fills the screen.
