Raid gold rewards corrected

Since an update earlier today, a solo raider received a raid's whole gold pool. That was never intended. Raid gold is now split by party size, but never by fewer than 5: parties of 5 or more are paid exactly as before, solo and small groups get one raider's share (e.g. King Gloop solo 8,000 instead of 40,000).
