[DGD] HTTP/1.1

[Shentino]

In the hopes of avoiding all the CGI garbage (and seeing hazards in
setting up DGD as a cgi starter), I thought I'd study the RFC and try
to implement a web-server directly.

So far, my hello_world object is able to send and read a form, but
discovered much to my dismay that elinks chokes on CRLF, even though
that's specified by the standards.

Any other subtle "gotcha"'s I need to worry about?  I suspect paying
attention to the "user_agent" header is a good idea, but I don't know
how to do that yet.
