'sort' command renamed to 'whosort'
(in analogy to gamessort, so it is more consistent)
"Game is titled" info mesg will be no longer displayed.

No visible changes:
setecho(): replaced old tty struct by termio struct and ioctl().
Integrated new struct MessageTypes from Tweedie.

Info messages from server are now displayed in the server window
(in board mode). They are prefixed with "> ".
Server err mesgs are prefixed with "! " and displayed in the server window, too.

No option -s any more.
Host names without a '.' are considered shortcut host names.
Revamped doargs().

Remove '!' around shouted mesgs.

In full-screen server mode, long messages from server will be printed in
chunks, too (like in board mode).

Increased a few constants to prevent core dump with 'who' command.
