Christian Ehrlicher 13426aff24 Cleanup QtWidgets animation examples
Cleanup the QtWidgets animation examples:
 - use nullptr
 - use normalized includes, remove unused includes
 - fix style
 - fix crash of sub-attaq when the game ended (error during range-based
   for loop porting)
 - don't use keyword 'final' for a variable name
