First commit. Squares work, but code needs restructuring.
Active shape and queued shape appear. No movement yet. Committing at a good landmark.
About to refactor and turn shape.squares[4] into a pointer array
Game works! Pieces behave as expected, the score updates on the screen, gravity works, lines clear. To do: menu screen, game over screen, high score table, sound, etc
