Subject: Mantis#1422. Thank you kindly, Xantor for a patch that : - volume
 doesn't change with a new llLoopSound(same sound, new volume); -
 SendFullUpdateToClients sends 0's in all sound related fields when there's no
 sound on the prim, thereby improving the amount of data being sent out on
 these prims (fixes zeropack) - Removed some code duplication between
 llStartSound, llLoopSound and llParticleSystem() calls
