[crossfire] Improving IRC availability with a chat bridge

[Rick Tanner]

After discussion and raised concerns about privacy, questions answered, etc.

My thoughts:

* Proceed with the implementation of a IRC & Discord bridge
* Two month archive history in Discord
* Channel topic update on IRC to alert users that conversations are
logged in Discord for two months
* Same guidance and recommendations on both channels in regards to
civility (or right now - IRC channel guidance applying to Discord channel)
* The bridge goes live at the end of the month or around Mar-1-2019

Feedback from anyone else on this?
