correct Research Unix edition "appeared in" use in HISTORY

Starting from "Combined Table of Contents" in Doug McIlroy's
"A Research UNIX Reader" a table of which edition manuals appeared in.
Checked against manuals from bitsavers/TUHS and source from TUHS where
available.

Ingo points out there are cases where something is included but not
documented until a later release.
