Light damage

Usage:
Light damage shares the following properties with Holy damage:
 * Light damage is a damage type caused by some monk weapons.
 * Light damage does not ignore armor.
 * There are no skills that cause light damage.
 * The skill Judge's Insight causes Holy damage that does not Ignore armor and therefore behaves exactly like light damage (with added 20% armor penetration).
 * Light damage is neither physical nor elemental damage.
 * Nothing protects specifically against Light damage.
 * Global damage reduction, from equipment with damage reduction bonuses or enchantments such as Aura of the Lich, does reduce Light damage.
 * Light damage deals double damage to undead creatures like minions.
 * The Necromancer's Tormentor's Armor and Necrotic Armor take additional damage from light damage.
