Timezone doc patch

Appended is a doc patch that removes tables B-4 and B-5 from Appendix B and
integrates information from there into other parts, mostly into section
8.5.3.

I still havent gotten a reply to

http://archives.postgresql.org/pgsql-hackers/2006-09/msg01590.php

so I didn't change those parts.

Actually, this was one of the outstanding open items on Bruce's list.
