Read mob rune damage and natural attacks from RuneTemplate

AbstractCharacter mob damage/ATR and CombatManager.getNaturalAttack now
read RuneTemplate._runes instead of the legacy ItemTemplate map.

Parity (offline, static_item_templates vs COBJECTS/RUNE, 2695 runes):
0 differences in rune_min_damage, rune_max_damage, rune_attack and
rune_naturalattacks. All 2366 runes with natural attacks use the
10-value layout. No value changes expected.
