[7904] Change creature damage calculation formula. Author: Seizerkiller

* Add new creature_template field `dmg_multiplier`
    * Make attackpower include in creature damage not dependent from attack speed.

    NOTE: included in sql update recalculation for creature damage related fields only make
    temporary possible usable values. Real values need revisited by DB devs for correctness.
