 and a cleaner/smaller generated torrc.

 I also added an associated host field for each one.

 Yes, I don't believe we use this by default. it can be set in tor-android-
 service if needed.

 > Please pass this directly to tor, we shouldn't change the intended
 behavior if the app configures a 0 or negative port number. Tor will emit
 a warning which the app should handle itself.
 The negative int or null value is treated a "magic" number for "auto".
 This is really because tor config accepts strings (auto) or int types for
 port so we have to be able to handle this somehow.
