[plt-scheme] Racket v4.90.0.1 is available for testing

Version 4.90.0.1 is now available for testing from

  http://pre.plt-scheme.org/release/installers/

Note that this is not available from the usual download site.

If all goes well, this will turn into the first Racket release (which
will be version 5.0) in about a week.

Any help and feedback in testing this new release candidate will be
much appreciated.
