[Gameplay] Spirit Visage applies twice on Blade of the Ruined King's bonus damage

Pretty broken. Don't know why none realized until now.

The healing is basically calculated this way: Ad*resistances*lifesteal*1.3+BrkBonusDmg*resistances*lifesteal*1.3*1.3

Also, Heal power works on bork's damage, don't know if that's intended. (is it considered a drain effect?)

PS: It applies twice only if the healing is taken from lifesteal, it doesn't apply twice if it's taken from DD/Hextech
