Generic humanoid creature dies sound effect

[Arcanorum]

Notes

Will need to add some kind of entity taxonomy configuration system to entities that is available on the client, to play the appropriate death sound.

Acceptance criteria

• When a human/goblin/vampire etc. creature dies, a gasp sound should be emitted to all nearby players.
• Perceived volume should decrease with distance from the creature, up to a cut off point (done in code).
