No very good reason, but I've occasionally wanted to frob it to see if it
makes any difference to problems I'm having, and it was easy.
Tested that it does actually cause keepalives on Windows (with tcpdump);
should also work on Unix. Not implemented on Mac (does nothing), but then
neither is TCP_NODELAY.
Quite a big checkin, much of which is adding `keepalive' alongside `nodelay'
in network function calls.

(we didn't before) - `ssh-termspeed'.
In the process, I've removed the individual controls on the Telnet and
Rlogin panels and replaced them with one on the Connection panel (since they
were backed by the same storage anyway).
The terminal speeds sent in SSH are logged in the Event Log.

hazard. I considered removing it completely, but I can't rule out
the possibility of an OS that actually takes security of its
terminal devices seriously, and which might be able to make sensible
and safe use of this feature.

clears, and also to temporarily push the primary screen contents
into the scrollback while the alternate screen is active and bring
it back afterwards.

to pieces, and put it back together in a new table-driven form.
config.c sets up a data structure describing most of the config box;
wincfg.c adds in the Windows-specific options (so that config.c can
also form the basis for Mac and Unix config boxes). Then winctrls.c
contains a shiny new layout engine which consumes that data
structure, and windlg.c passes all WM_COMMAND and similar messages
to a driver alongside that layout engine. In the process I've sorted
out nicer-looking panel titles and finally fixed the list-boxes-are-
never-the-right-size bug (turned out to be Windows's fault, of
course). I _believe_ it should do everything the old config box did,
including context help. Now everyone has to test it thoroughly...
