Racket: better help commands
For some reason that i don't fully understand, evaluating a function in the racket/base namespace first thing after loading errortrace breaks the help macro (!). This patches provides a workaround by actually invoking help first thing when Geiser starts, with alibi that it serves to preload the help index (in a separate thread). While i was at it, i improved the message printed in the minibuffer when no help is found.
