Update hidden service website page with Unix socket info
We should update the https://www.torproject.org/docs/tor-hidden-service page with some information on how to setup an hidden service with Unix socket.
Since 0.2.6, both SocksPort
and HiddenServicePort
support Unix socket. Example:
HiddenServiceDir /your/HS/dir
HiddenServicePort 80 unix:/path/to/socket
For service that supports unix socket like nginx (http://nginx.org/en/docs/http/ngx_http_core_module.html#listen), you only need to point it to "/path/to/socket".
