* Uses a hierarchy of WeaponClasses -> Weapons for performing attacks, with WeaponClass having a set of styles and associated Attacks for those styles. Weapons and their classes are built with an easy to use and clean DSL. * Adds a BonusContainer mixin, so that Equipment, Weapons, and WeaponClasses can all have their own set of bonuses which apply to the player. * Allows attacks to be queued to the Mobs CombatState instance from external code, allowing e.g., NPCs or auto-cast to queue attacks to be executed.
