hgweb: drop support for "manifest" parameter
AFAICT (but note that this is the first time I look at hgweb code),
the "mercurial" query parameter was removed from rendered pages in
36fa5db79dd5 (hgweb: convert gitweb to NWI, 2006-10-05). Search for
"manifest=" in that diff to see why I think it was removed. It's about
time we stop looking for the parameter in requests.
