Twilio integration

First round draft at attaching Twilio.

Set the custom rake up for scanning reservations, finding the user, and passing those parameters (ActiveRecord Objects) to twilioText which then performs the necessary actions.

A test will require us to sync up data and then create an appointment for 1 day from current (DateTime.now.day) and then run the custom rake.  I think we can do `heroku run rake <rake_name>` or we can just do `rake <rake_name>` from Rails Console.  I'm going to investigate after updating.

After copious testing will I finish setting up Heroku Scheduler (already deployed) to run as necessary.
