Updated documentation, list etiquette, and radiusd -X

Matthew Newton has written some excellent documentation on how to use the mailing list: http://wiki.freeradius.org/list-help Topics include how to ask good questions, why the debug output is important, etc. I suspect that from now on, answers to bad questions will simply be a link to that page. Since the debug output can be long, opaque, and intimidating, I've also written a guide. The guide explains what the various messages mean, and what the server is doing: http://wiki.freeradius.org/radiusd-X I hope these two guides are useful. Alan DeKok.
