req.accepts: */* wildcard fix.

Look for '*/*' anywhere in the Accept header instead of only supporting it when it's the exact value of the header.

IE8 sends:

    Accept: image/gif, image/jpeg, image/pjpeg, image/pjpeg, application/x-shockwave-flash, application/x-ms-application, application/x-ms-xbap, application/vnd.ms-xpsdocument, application/xaml+xml, */*

for which req.accepts('html') returned false.
