[racket] Try Racket

First, well done! It works great.  Eli, what would it take to host
this at `try.racket-lang.org`?

A few small things:
 - the error messages for `circle` don't have any indentation, unlike
what they do in DrRacket
 - I think the "Go!" section is too long for a single box -- it didn't
quite fit on my monitor.  The "Lists" section is also long.
 - Typing multiple line text causes it to be indented slightly wrong.
 - The identifiers in the text should be set in typewriter font
 - There's some wrong indentation in some of the code in the prose.
 - Loading the planet package seems to take quite a while, which means
it's probably actually loading it.  Best to make sure that doesn't
 - An older version had a nice message if you typed 'next' on the last screen.

And a few larger things:
 - You might be able to add tab-completion for identifiers, using the
namespace the way that the `readline` library does it.
 - The section on local binding in the tutorial probably needs
revision, since it encourages `let` instead of internal `define`, but
modern Racket style goes the other way.
 - It would be great to hyperlink parts of the text to the
documentation automatically.  Perhaps the way the examples on the web
pages work would help [1].  This is probably complicated to set up,

Again, awesome!
