[plt-scheme] Default (define-struct ...) behavior

OK. I'll buy that.

It came up mostly because some of my students are experimenting with
full Scheme, and they're accustomed to the constructor syntax. With an
inspector, you get a distinct printed representation that still lets
them see what the contents of the structure they created/are testing
in the interactions window. If, of course, one says
"(make-inspector)", which is a rather opaque.
