An option for real repl output.

There have been many requests to expose the products of
the repl in some way outside in-memory. This does that.

  scala                        # usual in-memory behavior
  scala -Yrepl-outdir ""       # make up a temp dir
  scala -Yrepl-outdir /foo/bar # use /foo/bar
