move away from OFTC to new functional, Tor-friendly IRC network

Everyone having issues using current OFTC. This is not a support issue. The problem is with OFTC blocking Tor connections. Not configuration.

I am not positive about this situation to improve over time. Enough time has passed. OFTC does not seem to care/prioritize this issue enough. I think it's well justified to make the change.

Ideally, the whole Tor community (Torproject, Tails, Whonix, Qubes, ...) would switch to a new, functional, Tor-friendly IRC network.
