Backbone js Testing Infrastructure with Jasmine
Created course_spec example

* Tests courses_index view
* Added jasmine-jquery.js and sinon.js libraries
Reduced testing redundancy into spec_helper

* FakeServer setup moved
* Server Response logic moved
Change to fixture implementation

* To fight Access-Control-Allow-Origin
* Now, every fixtures/json file should modify and inject an object or
  list into the fixtures object.
Pulled master into branch
