TrophyRace: Fix game never eliminating any hogs after a hog skipped or ran out of time Warning: This commit _might_ invalidate past records, but I'm not sure if this is actually the case. Note that only the eliminiation part of the script is touched, not the actual race logic. Even if records are actually broken by this, I and sheepluva have decided that it's more imporant to fix this very, VERY stupid and old bug than to preserve records.
