Site docs update. Incorporates the comments from the earlier patches sent 31st August "Site docs update - work in progress". As David suggested I also ran webby so this patch includes the site/output files (html). Because of this git send-email complained about 'lines longer than 998 chars' so I had to use the --no-validate option to get around it. If you have problems applying please let me know and I'll resend without the /output (though you will then have to run webby yourself to see the actual site html),
