Iteration 4 - Show and Add Ratings

[peeratmac]

• User should see their own ratings ONLY if they are logged in

- Movie's average rating is shown if no one is logged in (Movie's average rating is always shown regardless of isLoggedIn status)

- User should be able to submit their rating for a movie (when logged in)

- Integer 1 to 10 only for rating (think Dribbble for inspiration)

Note: one rating per movie, the limitation here is where once rating is submitted, the only way to change is to make a DELETE request, then resubmit with a new POST (this will be done after the implementation of this ticket)

PR #45 should complete the work of this ticket.
