Don't use FORWARDED_HOST when getting referer values.

Browse source 
HTTP_X_FORWARDED_HOST is supposed to be used by proxies to indicate the
original HTTP_HOST value. It has nothing to do with referer values.

Since the HTTP_X_FORWARDED_HOST is intended to replace the HOST header
in proxied setups, add a trustProxy parameter to host() and default it
to false. This maintains existing behavior and allows people to access
the proxied value.

Fixes #2537
