Title: Fixed a few misprints in lesson 7

Mainly, the function free_squares changed name during the lesson. Also fixed indentation inside free_squares.

It would also be possible to remove the initialization of shape and the declaration of shape as global inside click() as shape is no longer used since the player always uses O and the computer uses X. Though, that removal might lead to more confusion than simply keeping it in?
