Docs on web site

Hi Vince. I've put the 7.1 docs on the web site in the appropriate
place. Nice auto-generating web page stuff btw. 

I modified and compiled *but did not check into cvs* build.c to get nice
references for the new Developer's and Reference docs.

OK? If you want to inspect the changes, then commit (or tell me to) that
would be great. TIA

The web site itself seems very slow at the moment; some robot process is
chewing up lots of CPU so perhaps that is the reason. hub.org (which may
actually be a different machine) is quite fast otherwise.
