Subject: [PATCH] Expand World.spawnParticle API and add Builder
Adds ability to control who receives it and who is the source/sender (vanish API)
the standard API is to send the packet to everyone in the world, which is ineffecient.
Adds an option to control the force mode of the particle.
This adds a new Builder API which is much friendlier to use.
