Implementation of the arcade classic Puzznic

 As the original game, your mission is to clear the level of
 bricks, this is done by moving the bricks about, when two or
 more bricks of the same kind are next to each other, or on top
 of eacho ther, they will disappear and points will be given.
 The level has to be cleared of bricks before the time runs out,
 or you will lose a life.
