Add Widescreen mode option to normal play.

[Boa Jacque]

Tiles beyond -X- from player could be blackened with an overlay or something to balance it out so that players without widescreen aren't at a disadvantage.

Also, since when did having the greatest advantage matter to this extent? There are many ways to gain "advantage" over other players as it is, few of those that exist also do something nice like what widescreen does.
