Bug fix and high score sync — Always Surrender Steam update #515001

In rare circumstances the high score save file could become corrupted (when moved for example), resulting in Always Surrender not being able to launch. This update fixes this issue but will result in high scores being recorded as zero only if the corruption occurs. It is also now possible to sync your high score from the leaderboard to the local save if needed. Go to the leaderboard and once loaded press the button assigned to Surrender to do so. This will need doing for each mode separately.
