fix: a tetromino can't appear twice in a row, and rotation is no longer preserved

Browse Source 
Tetrominos can now appear twice in a row, and rotation is no longer
preserved for each shape.
(if you rotated a specific shape 90°, now whenever you encounter this
shape, it spawns with a 90° rotation, and so forth)
