[OpenAFS] Quick Start Guide updated for Kerberos v5

[Simon Wilkinson]

I've just made an HTML version of the current OpenAFS Quick Start  
Guide for Unix available at
http://homepages.inf.ed.ac.uk/sxw/OpenAFSQuickStart/book1.html

This includes a load of changes that were made a few months ago to  
update the guide so that it describes the process of setting up a  
cell using Kerberos 5, rather than kaserver. As the main author of  
those modifications, I'd welcome feedback about those instructions.

Cheers,

Simon.
