Subject: [PATCH] allow documentation to be configured

Add --disable-doxygen-html and --enable-doxygen-pdf options to the
configure script, allowing user to change the defaults.  These
update the proess of munging the Doxygen configuration file to
use the settings thusly provided.  Add options in README.
