This patch adds Fred to dloader.  Please let me know your thoughts.
It looks roughly like this:

=========================== DragonFly BSD =========================
                                 |
         [logo]                  |  1. blah
                                 |  2. blah
                                 .
                                 .
                                 .
                                 |
===================================================================

There's no limitation (other than sanity) on menu entries.  However
the logo is currently arbitrarily limited to 17 lines.  It would be
easy enough to allow for taller logos.  The logo is currently 20
characters wide so care needs to be taken when making longish menu
entries.

Thanks,
Joe
