leave Freenode for oftc.net

This is becoming a long story, but basically Freenode was hijacked,
policies were changed to allow racism and bigotry, trolls have been
promoted to opers, and opers are hijacking channels. It's a shame,
really, but nothing we can do it seems:

Moving to OFTC since that's where most of my other channels (Debian,
Tor) are.
