Pre-commit review requested

[Tom Rhodes]

Any -doc committer want to review the following patch.  It is by no
way an in depth cleanup, but it will take us (myself anyway) one
step further toward my goal of a good security chapter.

This diff:

o Adds <application>, <acronym>, and other tags as required.
o Uses the &os; entity.
o Cleans up the introduction by pointing out what
  version of Kerberos is in what FreeBSD Release.
o Modifies <indexterm> and title's to help seperate KerberosIV and Kerberos5.

I'm only looking for either objections or "please commit"s and would rather
not bounce this around for the next three days.  Thanks!
