Fix reading news for past games triggering lotto win
Fix reading news for past games triggering lotto win

Since the lotto winner selection code is run when reading the news,
this could be triggered for past games if there were outstanding
lotto tickets.

To fix this, we simply return immediately from `checkForLottoWinner`
if the game has already ended.

Thanks to Rain for reporting this issue!
