Improvements (old stuff)
Re-written using OO, draws the game and an I piece to screen
Checks that piece is not out of bounds, copies (instead of moving...) the piece left, right or down
Changed the arrays s.t. they are called as array[x][y] in code (easier...), changed printing accordingly
Good night (cleaning...)
Changed how pieces are drawn, added an 'up' move
Improved the moving of piece (now 'discrete'), added global variables for FPS, MOVE_TICKER
