Message:

Tetris on the way to get completed. I fixed some bugs concerning rotation, false brick placement on brick-brick collisions, clearing multiple rows and added a preview brick feature and a basic hud.

  *BUG c) destroying the old stones causes segfault -> WeakPointer as solution ?
  *BUG d) wrong collision detection: sometimes stones "bounce off"
- *BUG e) multiple rows are not cleared in one round
