This is an easily overlooked setting, let's make it easier

Modem result codes. Oh, the memories...

Anacron sends mail From: Anacron <root>, so deal (convert to root@youraddr).

Also, gracefully handle a forgotten recipient list.

warning: ‘%s’ directive writing up to 16384 bytes into a region of size
between 1 and 16385 [-Wformat-overflow=]

warning: argument 1 value ‘18446744073709551608’ exceeds maximum
object size 9223372036854775807 [-Walloc-size-larger-than=]

... rather than just return false.

This will make debugging this type of issue much easier in the future.
sendmail.js was allowing empty recipient_list array arguments and the MsgBase
.status was 0 and .error just an emtpy string - unhelpful.

warning: ‘checkStamp’ accessing 20 bytes in a region of size 11
etc.

Direct users to Program Settings->Startup Screen Mode for initial/default
screen mode.

Wording update for Startup Screen Mode help.

Indent the File Locations less as these paths are usually much longer on
Windows and is ugly when wrapped here.

warning: ‘%s’ directive writing up to 128 bytes into a region of size 74

(like we do for Message Groups and File Libraries already)

Use the Synchronet-supported FTN/QWKnet routable addressing in the from fields
of messages posted via those network types. Using the mailutil.js
fidoaddr_to_emailaddr() function that was apparently created for listserver.js
but then made unnecessary (and thus unused for several years).

I think this addresses the concerns from issue #487. Reading a message via
NTTP (using the Synchronet NNTP service) in Thunderbird, one can now reply
to sender via email and it "just works" so long as the sysop has configured
the network support for those net-types correctly and Thunderbird is
configured with the Synchronet mail server as its SMTP server to use for that
newsgroup folder. Whether the Synchronet mail server is configured to use
direct delivery or relay is not relevant (though mentioned in the issue
description).

Move the Mail Server->SendMail* settings to their own sub-menu.

Added popups while reading sbbs.ini

Fixed reversal of logic for FTP Server->Sysop File System Access option

And display an error message upon failure.

Still needs online help text.

This allows the [Global] section to be applied to each server section correctly

Before this change, changing BindRetry in the global settings would result in
the original global BindRetry value being added to each server/section of
the sbbs.ini file.

The address needed to be converted to a string first.

Remove values, not keys, when setting a key with a global default.

Use UInt16 functions for getting/setting TCP ports (this fixes an issue with
the FTP PasvHigh port being set to -1 (instead of 65535).

Use iniGetUInteger instead of iniGetShortInt for most other key values.

First sbbs.ini save support in SCFG, still experimental.

Remove trailing white-space (e.g. after the equals or colon following the key)
in iniRemoveValue().
