Seem to remember someone posting to one of the lists a while back
that the tutorial code wouldn't compile and/or run.  Found four
problems with it that will let it run.

1. Tutorial makefile had a recursive use of DLOBJS.

2. Some tutorial needed semi-colons added to many statements.

3. Complex tutorial didn't clean up after itself.

4. Advanced had a time-travel example.  Commented it out and
   put a line pointing the user to contrib/spi/README.
