step-6 phone images and links

- adding phone image and links to phone pages
- add end2end test that verifies our phone links
- css to style the page just a notch
step-7 $route and app partitioning

  views
  - Create PhoneCatCtrl which governs the entire app and contains $route
    configuration
  - Load the ngRoute module
  - Map `/phones' to PhoneListCtrl and partails/phones-list.html
  - Map `/phones/<phone-id>' to PhoneDetailCtrl and partails/phones-detail.html
  - Copy deep linking parameters to root controller `params` property for access
    in sub controllers
  - Replace content of index.html with [ngView] directive

- Create phone list route
  - Preserve existing PhoneListCtrl controller
  - Move existing html from index.html to partials/phone-list.html
- Create phone details route
  - Empty placeholder PhoneDetailsCtrl controller
  - Empty placeholder partials/phane-details.html template
