RFR - JL add user cp

User can visit profile page, the following actions can be performed:
1. update info (email, password, profile photo)
2. view all reviews the user has posted
You could actually combine this test with your first spec.  It has more or less all the same setup, so you can just add an expectation to that spec that says you also expect to see the user's actual reviews:

```ruby
    before :each do
      @user = FactoryGirl.create(:user)
      @reviews = FactoryGirl.create_list(:review, 2, user: @user)
      sign_in_as(@user)
    end

    scenario "view profile page" do
      click_on "User Profile"
      expect(page).to have_content(@user.username)
      expect(page).to have_content(@user.email)
      expect(page).to have_content "Your reviews"
      @reviews.each do |review|
        expect(page).to have_content(review.body)
      end
    end
```
