Redo with promises

[shiffman]

Should I redo the earlier bot examples with promises? It's tricky b/c I'd like that to be available, but I used callbacks in the videos so would make it hard to follow along. Maybe I should make both available!

If you or someone else is going to take the time to re-factor away from callbacks I would suggest skipping Promises and generator functions and jumping straight to async/await.
