The sound emitter component

Within the entity component system paradigm, every possible entity parameter or feature is represented as a component. Emitting sounds is definitely one of those features.

Before that, however, let's define the types of sounds an entity can have:

enum class EntitySound{ None = -1, Footstep, Attack, Hurt,Death };
