Add support for the irc+insecure address scheme

Some servers do not support TLS, or have invalid, expired or self-signed
TLS certificates. While the right fix would be toi contact each server
owner to add support for valid TLS, supporting plaintext upstream
connections is sometimes necessary.

This adds support for the irc+insecure address scheme, which connects to
a network in plain-text over TCP.
