Reorganizing Gemfile, adding gems to be used later for points_controller.
Add factory_girl; use expect syntax only for rspec
Adding basic "point" logic to represent student participation score:
JSON only (no HTML) entities -- for internal API use

  * Model
    - migrations (base, and one added by paranoia gem)
  * Controller
  * Views for index, created point, show

  Specs:
    * factory for model
    * controller spec
    * routing spec (minimal) [removed misnamed point_routing_spec.rb]
    * request spec (stubbed placeholder)
View errors for JSON, fixed
* Added and normalized version numbers for Gems in Gemfile to 2 digits, adding version number in most cases;
* Adding HAML for cleaner markup;
* Added newline at end of app/view/points/create.json.jbuilider
