Bitlbee: Slack, Hangouts & Facebook via IRC gateway

Having multiple clients to handle multiple networks is a mess, especially the Slack client which is really heavy and annoying.

Slack is deprecating its IRC gateway interface on May 15h 2018.

Bitlbee is an IRC server working as a gateway to different IMs.

Optionally Bitlbee can be compiled with LibPurple to support even more networks, like Slack and Hangouts.

Here are some notes for Slack, Facebook and Hangouts to be enabled with Bitlbee.
