excito B3 webinterface: dirport required

The excito B3 webinterface to configure tor (/admin/network/tor) in excito B3 v2.4.1.1 does not allow you to enable tor without specifying a directory port. (non-exit and exit modes)

This requirement is artificially added by the webinterface.

Tor certainly allows you to run relays that do not offer a dirport.
