Add message buttons

Here is some progress toward message buttons for setting attributes.

It doesn’t actually update the database 😁 but that shouldn’t be too hard

We are testing this out in the LGBTQ in Tech Slack. I’ll collect improvements here:

• [x] have yes/no ordering the same between manness and pocness
• [x] add a final summary after the final question
• [ ] check Slack verification token
• [ ] add configurability of message buttons, because it won’t work without setting up a Slack app perhaps?

Also a note to self that after getting the token and restarting the Heroku application, the bot couldn’t start up because it hadn’t been invited to its verbose channel. It should just handle the failure to join and speak in that channel.

Based on feedback in the community, here is the latest interaction:

There’s a visible history of the interview as it progresses. A question with response buttons is replaced by the question with the answer you chose. Now we must decide how to integrate this with/replace the current interface, and then this can be merged.

(I don’t know why the text is grey and I am not pleased.)
