Scripts/Icecrown Citadel: Added Professor Putricide script

Scripts/Icecrown Citadel: Fixed Professor Putricide gate opening when both Rotface and Festergut are dead
Scripts/Icecrown Citadel: Added script updating entries of NPCs at Light's Hammer depending on faction
Scripts/Icecrown Citadel: Rotface should not pick main tank as target for Slime Spray (removed debugging code)
Core/Spells/Conditions : Spell script target condition now accepts ConditionValue3 as affecting effect mask (only search targets with matching mask)
