- Added support for SMP systems to etc/rc.d/setiathome.sh

- Added etc/setiathome.conf with options to set the nice level, the max.
  number of processes to run, the working directory, and the the user id
  to run as.
- setiathome.1 was missing from Makefile (and +CONTENTS subsequently)
- Updated the man page to reflect the changes.
