Serve all output types on i.z.gd; redirect i.zk.gd to it

i.z.gd now takes ?output=txt|json|xml|csv|html (?nice kept as an
alias for html). i.zk.gd becomes a plain nginx 301 to i.z.gd, so the
service no longer routes on Host.

ipecho

Go replacement for the PHP "what is my IP" pages on z (see legacy/).

i.z.gd: ip, reverse DNS, user agent, unix time; ?output=txt|json|xml|csv|html (default txt; ?nice is the old spelling of output=html)
i.zk.gd: old domain, nginx return 301 https://i.z.gd$request_uri (no backend)
m.z.gd: plain nginx return 302 https://app.fastmail.com (no backend)

Runs as nobody on 127.0.0.1:8490 behind nginx, which passes X-Real-IP (only trusted from loopback). All output is escaped for its format.
