Added Win and Loose Animation + optimized Bomb handling

- Now two little animation (ninja smiling, ninja crying) will show game won, game lost

- added an internal game_manager as simple way out for "race conditions" (just delete and load the complete main loop)

- now different bomb types will execute one after another

- fixed a bug regarding smoke bombs (which weren't deleted in the same turn)

- removed smoke bomb animation (since it is ugly)
