Refactor & Bug Fix

`game.ts`
 - fixed score on new game

`Obstacle.ts`
 - made distanceBetweenPipes and startX public
 - moved initialization of distanceBetweenPipes and startX to game.setupGame()

`Pipe.ts`
 - created move() method to move the pipe

 `Raspberry.ts`
  - added constant variables for Raspberry size
