[racket] Unicode art

Thanks. Matthew also poked around on the various platforms and it
appears that setting the spacing to 0 makes DrRacket match standard
windows editors and makes the maze look right, but it doesn't help on
other platforms (on mac os x, it isn't clear what to do and under unix
it already worked).

So I've pushed a change to DrRacket that adds a preference. The
preference defaults to "no additional spacing" under windows and "one
extra pixel" (the 5.2.1 behavior) everywhere else.

Please let me know if things start to look strange elsewhere!

Thanks,
Robby
