Eliminate Samba configuration.  Sorry, but this was another one of
those ideas that, like the Apache server setup, was well-intentioned
but doomed to fail in the face of change.  That and the fact that it
shouldn't be part of the installation tool, it should be part of the
post-installation setup tool (which we need to write).  Combining the
two utilities into one utility was my first conceptual mistake.

Apologies also to Coranth Gryphon, who worked hard on the Apache
and Samba server setup code.  These features were quite useful
for awhile, if that's any consolation, I just simply had the wrong
ideas about where to put them. :-(
