RFC: Create a new and nice IRC log

[ravage84]

@ionas reported in cakephp/docs#4045:
Found this by accident on some github posts:
https://botbot.me/freenode/gratipay/2013-10-16/?msg=6935850&page=1
The old log interface could be made available as an archive.

We already have a new and nice IRC logging now, it's called Slack :P

I believe https://github.com/cakephp/cakebot is the repo for code that powers irc.cakephp.org

I agree with @ADmad , we have slack.
