splash links

1. freecode. Between the fact that the site's been in suspended animation
   for a year and there's been all of this sourceforge unpleasantness just
   lately, it would be nice not to link to them.

2. In my opinion, it wouldn't do any harm to remove the "News", "Additional
   Stuff", and "Essential Readings" links, as they have something of an
   Internet Circa 2002 flavor (in some ways it's a shame to think how
   pioneering projects like Project Gutenberg lose their preeminence as the
   pioneer days end, but I suppose that's the way of things).

PS Been running on the 3.0.5 branch here, of course, and everything's been
fine so far.
