See The ".onion" Special-Use Domain Name

This would prevent any leaking of requests to onion domains when incorrectly resolving through DNS.

One this to consider here is to do this before any searches, i.e. example.onion should not use the search list in the config, we should not e.g. search on example.onion.example.com
