[racket] auto-spacer

I think that could work well in drracket. It is careful never to
insert tab characters into your program when it indents (for the
problems listed in the beginning of that essay) so there is relatively
little existing use of tabs.

And drracket's editor class is now implemented in racket, so anyone
can add stuff to it (without fear of segfaults :).
