Now you can get varnish to gzip or gunzip objects as they are
received from the backend by setting

	sub vcl_fetch {
		beresp.do_gzip = true;
		beresp.do_guzip = true;
	}

They will only do something if the object is/isn't gzip'ed already
(according to the beresp.http.Content-Encoding header) so the above
silly-ish example will compress al uncompressed objects and decompress
all compressed objects.

NB: Lots of errorchecks not implemented yet.
