tor-hs: cleanup tor-hs.conf

Replace boolean "true"/"false" with more frequently used 1/0.
This may avoid configuration mistakes which is critical for Tor.
The Luci app anyway will set it as 1/0.

Make sections named. This is not required but again safes from mistakes when executing uci command.

Uncomment sections but disable them by default.
Then in a Luci app a user can quickly figure out what to change.
Ideally a user may just enable the config and start using it.

In the nextcloud config use a single 80 instead of 80;80.
This simpler configuration is now supported.

Instead of "Hidden service" the Tor team now uses "Onion service".
