Title: replacing window by $window

Injected $window in the service for replacing the reference to window global object.
$window is a reference to the browser's window object. While window is globally available in JavaScript, it causes testability problems, because it is a global variable. In angular we always refer to it through the $window service, so it may be overridden, removed or mocked for testing.
