Winning the game now correctly submits the time to the stats screen and
moves there
TODO:
Ensure when moving back to the game via the intent stack (back button)
that the game restores. Done by saving the state into the bundle.
Make stats screen better looking, titles, main menu button etc
*When back button is used on stats screen move back to mainmenu
*Add a name to the user winning times

* Unsure of. Need looking into
