Small bug fix

I’ve just released BETA 3 of WINNUKE. I received a report of an error message appearing when the game saved the scoreboard.

Essentially, when the game saves the score, it loads the scoreboard from file and then figures out whether your score is bigger than the scores on the scoreboard. On first run though, the file doesn’t exist and I’d forgotten to check. It doesn’t actually affect writing the scores though luckily so that’s good.
