I just want this in the history in case I ever want to play with
the concept again.

The fg/bg values all have multiple representations, and some bits
have extra meanings, so inequality there doesn't mean they're not
the same colour.

This fixes an issue where the *second* drag select on a screen
would not highlight blue backgrounds correctly.  The background
colour gets the "pixels set" bit flown because of how
restorescreen() works, which caused this to "know" it's not blue
and use a blue background.

A (good) argument could be made that savescreen()/restorescreen()
shouldn't result in any changes, but since uifc32 doesn't directly
use colours that aren't represented by legacy attributes, there's
no need for it to get tricky here.

SlyEdit: Display a user inactivity warning message (configurable)

See merge request !498

There's no need to set line = NULL since it's always overwritten.

Fix for issue #870

FF and VT both move down one line, scrolling if necessary.

The rest of the unsupported control characters have no effect
(ie: work like NUL)

Delete shows the delta.

Add ESC L and ESC M for insert/delete line.  Used by commando text.
Use a block cursor that blinks at 1Hz.
Discard invalid ESC codes.

Thanks Kirkman!

CTerm does not presently take any action for any of these, but it
does parse and ignore them.

<@Deuce> DigitalMan, also, as it turns out, Windows 7 was the last version of
Windows that supported processors without SSE2.

Since we're targeting Windows Vista and Windows 7 still, don't require FP
extensions that SBBS really won't get much benefit from anyway.

Resolves MSVC x64 build warnings.

Also fixes a bug with wrong sizeof argument used in readdir() (!)

I discovered the first case when FileBase.get_path() failed, but didn't
(immediately) throw an exception. Reviewing the other instances of
JS_RepoertError() calls found several that either reported a garbage (e.g.
NULL) string value or returned JS_TRUE.

The design pattern used a little in js_socket.c probably should be used more:

	if (JS_IsExceptionPending(cx))
		return JS_FALSE;
	return JS_TRUE;

... but that's more of a refactor than I had the stomach for right now.

It's Transfer-Encoding:, not Content-Transfer-Encoding:, and each
chunk has a \r\n appended to it.

With the latest change, *val will be \n after the last item, so
this avoids an extra loop through the loops.

1 - If cache-control header had more than one option, an infinite
    loop would occur.
2 - For TLS, if the remote closes the connection after the transfer,
    a "Complete" error would occur.

Together, these should fox ticket 191

Pasting mosaics won't work properly, but it wouldn't anyway, so I'm
not too worried about it.

Also, I can't seem to find anything I can paste separated mosaics
into, but that may just be due to Unicode 16 being so new.

Since we're translating in ch[0], don't use buf[j] for mosaic or
we'll lose the translation we just did.

In Beeb mode, receiving the byte on the left prints the one
on the right:

# -> #
_ -> —
` -> £

In Prestel:
# -> £
_ -> #
` -> —

Keyboard mappings adjusted so what you press is what you see.

Prestel and Beeb emulations are different enough that using a shared
switch statement doesn't really make sense.

This adds Mode 7 support for VDU commands 7 (beep), 23 (cursor only),
and 31 (move to X/Y, 0-based).

The rest of the unsupported commands don't seem overly useful in a
BBS context (disable/enable output) or I don't want to deal with
documenting and implementing ("Page mode").

Address warnings from Inno Setup 6, indluding support for both
"administrative" and "non administrative" install modes (!).

This means, if you have not installed SyncTERM previously, you should have an
option to install for "All users" (requiring administrative rights) or
"Just You".

When installing in non-administrative mode ("Just You"), the program will be
installed in your user "Programs" folder, e.g.
 C:\Users\<yourname>\AppData\Local\Programs\SyncTERM

If you previously installed SyncTERM in the common "Program Files" or
"Program File (x86)" directories (which assuming administrative mode, the
only install mode previously), then the installer will install again to
that same location (and require administrative access).

I'm still including a syncterm.lst download option (using curl.exe) because
the Web List feature is not working so great in v1.5. That option should
go away in the next release.

Seen disconnected users "stuck" in irc.js for long periods of time. Hopefully
this helps.

I saw this in my error.log:

evnt DELFILES !JavaScript  /sbbs/exec/delfiles.js line 100:
     Error: -110 loading file 'somefile.name'

Which would terminate the script. We don't need to do that, just log it
and continue on.

Other changes of no consequence.

Specifically, \x11 is not cursor on, and \x14 is not cursor off.
