Copy/paste without the update required a single character to have
seven different values... which is unlikely to actually happen.

The calls to cryptlib are still broken, so that's a to-do item.
e.g. calling cryptstatuSOK() in st_crypt.c init_crypt() throws an
exception:
"Run-Time Check Failure #0 - The value of ESP was not properly saved across a
function call.  This is usually a result of calling a function declared with
one calling convention with a function pointer declared with a different
calling convention."

<@Deuce> SyncTERM on MSVC really shouldn't be part of CI since it's not expected to work.
<DigitalMan> why not?
<@Deuce> Because it's not supported.
<@Deuce> So it's not part of the integration path.

Have js.on_exit() throw an exciption with a useful(?) error when the
scope already has private data, and that data is not an on_exit list.

This fixes #182.

This should be use in all the other places, but this was enough for
me to debug the issue at hand.

This behavior was cut/pasted from xtrn_sec.js but doesn't play well with logon events (e.g. SBBSIMSG list) that should pause before a following CLS. As reported by altere on the I, the R, and the C.

Count the read mail-waiting and compare to the total mail-waiting and if they're the same, then default to "No" for the "Read Your Mail Now" prompt during logon.

Also, pass the difference (the unread mail) to the LiMailWaiting logon-info line.

As requested by altere via I.R.C.

The AMD64 platform on FreeBSD is called amd64, not x64.

Since this was originally Pascal, there's a tonne of 1-based indexed
arrays, and the font ones were sized by number of elements, meaning
it was chock full of buffer overflows.  Also, the Pascal string
handling was crazy.

There were also some file IO issues floating around.

This fixes all of those issues and also Closes #179

By simply installing a supported 3rd party door game into your
"xtrn" directory, install-xtrn.js or xtrn-setup.js can automatically
discover and configure your newly installed door for Synchronet. Easy peasy.

Resolves issue #181 (great idea) by Michael Long. Deuce and others have had
similar ideas in the past.

Now, we don't have to rely on the authors of potentially-abandoned door games
to create and include a Synchronet install-xtrn.ini file. We can just do that
for ourselves and make installing all (known) door games super easy.

Many more xtrn/3rdp-install/*.ini files will be forthcoming!

Change SubSystem type from Console to Windows to resolve error:
unresolved external symbol _main referenced in function ___tmainCRTStartup

QUERY_STRING is defined (even if blank).

Always define it.

Most are simple memory leaks, but some would cause crashes, and
others would cause unexpected behaviour.

Options were added to arrays without increasing the size of arrays.
This caused the menu generated from them to depend on uninitialized
memory and potentially crash or emit garbage.

Let's try just caching the 3rd party stuff.
