Title: Feature/add notice for unsupported browsers

Adds the `UnsupportedScreen`. The `BrowserSupportable` mixin checks whether the current browser is supported (when entering a `RouteState`) and redirects to the `Unsupported` state if not.

This PR contains a pimped design for the `ErrorScreen`.
Also, it finally fixes the bug in the `GameController` which broke the app when trying to restart a race after it already finished (https://www.pivotaltracker.com/story/show/37679203).
