Hi all,

For some reason, constant Hash CGI::HTTP_STATUS lists only a very limited list of HTTP status codes. Programming REST-style
web services, I need many of the other status codes, too.

This patch fixes CGI::HTTP_STATUS to contain all standard HTTP/1.1 status codes, plus the WebDAV extensions which I
think can be very meaningful in a CGI context.

Greetings,
Pieter

(I'm about to send a whole bunch of patches, hope you won't mind.)
