Modified LevelBuilder - now, instead of creating boxes, it uses prefab file (which is still a box, but also a prefab).
Added CandyPlacer - this script places candies over each block created by LevelBuilder. Number of candies is random and by default it is between 0 and 5.
Added Reset - to make testing on mobile devices, now there is a "Reset" button.
Modified CandyPicker - number of picked candies is displayed on screen.
