NETWORK GAME IS BUGGY!!  It works on LAN, but not with slow connections.
NOTE: This has not been verified for a long time, please test it.

The screen will be screwed up if you copy&paste words that are not
displayed properly (i.e. you set your locale but your display cannot
handle the "symbols").

F1-F12, etc. are handled as ESC, so these will stop game, too.

If no word lists are available, play() ends in "press a key to continue"
loop until word lists are found.
