US06: Other Slack Integration Interactions

[takouhai]

As a normal Slack user, I wish to have the bot interact with the other installed to be able to get statistics and information on them.

Acceptance criteria

• When I make a Travis test error, I should be able to see how many times I’ve made it error.
• When I have a daily streak of checking in with Howdy, I should be able to redeem points for my attendance.
• When I miss a check in with Howdy, I should be reminded that I need to check in manually.

Design

@travis-ci: Build #69 (e7a02e4) of app@master by Moisés Ñañez errored in 1 min 3 seconds
@bot: Hey, @moises, that’s the fifth time you’ve errored a build this week! :worried:
=======
@howdy: [gives check in report]
    People who didn’t check in:
    @erick
@kely
@javier
@bot: Hey, @erick, @kely and @javier, you should check in manually since you didn’t check in with @howdy. 
Also, @kely, you’ve lost your five day streak. :disappointed:
