Use race rune natural attack damage for unarmed players

Unarmed base damage was a hardcoded 1-3 (TODO). Read it from the race
rune natural attack for the swinging hand (1-4 for all races), then
scale it with the existing formula, matching the client (0x46D200).
Falls back to 1-3 if the rune has no natural attack.
