+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.
