Removed unnecessary file 'master'
Fixed tests by changing to PhantomJS and fixing  putItemsResponse.json to follow valid JSON format
Fixed cookies and sessionStorage usage in user authorization. Using JQuery cookies instead of AngularJS because it is able to set expiration date to cookie. Http backend json mock data is fetched with Jasmine getJsonFixture instead of AngularJS $resource http wrapper. Updated AngularJS sources and cleaned index html files.
