Jeremy Stanley e858068643 Switch the IRC access check to OFTC
Make some adjustments to the IRC access check script so that it
works in the OFTC network now. Also update the channel config to
reflect the new ACL paradigms there. Remove our volunteer operators
temporarily until we can confirm their nicks there. Also rip out the
channel forwarding for unregistered nicks, we can work on readding
it there later if we determine it's necessary after all, but it will
need implementing differently anyway if so.
