Added "Check for new SyncTERM versions" link (to SourceForge).

as a zero-length string), and don't use any prefix "stuff" when handle_quotes

if one isn't specified.

For backward compatability with versions before 3.16c, this argument should
still be provided.

"high ASCII" is passed to the word-wrap function.

modifying the 'attr' field).
Also, only set the "SENT" attribute flag if the told not to delete netmail.
This will reduce the risk to those using SBBSecho without the -d option.

Don't pack netmail that has the "SENT" attribute flag set.
Set the "SENT" attribute flag in netmail (.msg) files so if they're not deleted
they won't be repacked/sent again later.

This should fix the crash on startup bug seen on Windows systems.

(on Linux) where the "total messages" value (stored in the SMB status header)
is stale when the header is updated in another open instance of the message
base.  Sorry, I forgot to complete the commit earlier than I originally said I
did.

(to testbuild.js), I suspect the setlocal call is causing the current error
level to not be passed up to the caller. If build.bat failed, testbuild.js
would not always detect the build failure.

When built withOUT the preprocessor macro WITH_SDL defined, ciolib.h doesn't
include gen_defs.h (perhaps it should), so the use of FREE_AND_NULL in this
file become function calls and the symbol is not found when linking.
This is why jsexec was not included in recent daily dev builds of v3.16.

padding after it, it wasn't previously considered the same prefix.

Fix prefix comparison by adding a function for it.

Add a great deal of comments for future-Deuce.

The old code unwrapped from the old width and rewrapped to the new width in
a single pass.  While this was more efficient, it was very difficult to work
on and understand the code.

Now, wordwrap() is a two pass process.  The first pass unwraps "paragraphs"
(defined as being the text between two hard CRs) and the second pass wraps
to the new width.  This makes it simpler to understand and debug.

This fixes some odd wrapping issues when quoting messages.

Lines made up entirely of whitespace always end with a hard CR.

LFs on write.

the mod state.  This should fix num-lock on Windows.

Other mod states (CTRL, SHIFT, ALT) are likely still messed up though.

any line that was ever damaged was always damaged, and it worked pretty well.

when updating the screen.

This should fix the weird long-delayed update issue.

the screen.  This fixes the phantom cursor issue.

For regular vstatlock things, only hold the lock long enough to copy the
variables that will be used.

For vstat.vmem stuff, create a separate reference-counting vmem structure
and a new vmem_lock so the memcpy() of the vmem won't block basic vstat
accesses.

This appears to fix the recently-added "blockiness" of screen updates in
SyncTERM, without risking deadlocks or unlocked accesses... the major issue
holding up a release.
