Add a context specific live chat

Slack is dope but I can't complete deliverables in slack

If you gave me the ability to talk in aha live in real time with other people about specific stages of development I don't know if I would ever leave aha.

Or just make it so that responses in slack to a activity automatically get pushed back to aha and appended to the object it's about. I would love to have all the info in one place
