implementation of Sound DB

Client sounds are cross-referenced with as many other DB-Types as possible. Including, but not limited to:
 * Character VOs (Errors, Emotes)
 * Creature VOs (Boss Dialogue)
 * Zone Music and Ambience
 * Sounds triggerd by spells
 * Sounds from general item/spell usage, creature behavior

Restrictions:
 * only one locale is supported. Choose wisely!
