Allow any domain name to be mapped to an IP

Browse Source 
This enables .onion domain names to be accessed by clients that are being
routed through the SOCKS tunnel by e.g. proxychains (assuming that the SOCKS
tunnel has been configured with a SOCKS outproxy that exits into Tor). If the
.onion is not mapped to an IP address, the client would attempt a DNS lookup
which would of course fail to find the .onion.

Clearnet domain names can also be mapped to IPs, but this is irrelevant as DNS
lookups work through SOCKS (via the configured outproxy).
