Minor error(s) page 220 onwards

Page 220 note that the last keyframe for elevator summon is at 0.29, not 0.28. The screenshot would also have to be updated.

Also note the ‘pip’ no longer leads to a popup, but opens in the inspector instead.

Page 221 endGame should be EndGame to stay consistent with the pascal notation used so far. This is true for other instances of this issue further down the book.
