Glossary wiki page

[ghudson@MIT.EDU]

We have sort of a bad habit of not defining acronyms and other terms
anywhere in the Kerberos code base--recent examples include FAST and
PAC.  It's not so bad if you're familiar with RFC 4210 and are
following the IETF krb-wg work, but it can be a bit mystifying
otherwise.  To help address this problem, I've created a glossary page
on k5wiki; it's at:

http://k5wiki.kerberos.org/wiki/Glossary

and it's linked from the "learn more about the code" page.  I've
seeded it with all of the acronyms I could think of off the top of my
head.  Please feel free to add others.
