* Does not create a response if blank answer
* Random show page (does not repeat)
* Styled invitation form
* Added table header to campaign show page / targets index table
Fixed query so called records are not shown during calls.
Initial JS functionality for target show page hides the nested response
attribute inputs if the target has not been called.
Disabled turbolinks / javascript to allow responses.js to work on
subsequent calls.
Asked caller if they spoke to actual target before gathering responses.
