Mantis#1406. Thank you kindly, Xantor for a patch that:

llLoopSound sends out one packet to clients in view, so it doesn't work anymore 
when clients enter later on, or the prim is modified in any way.
Solution: Stored sound data on prim, send full update instead.
llStartSound and llLoopSound now accept both LLUUIDs to a sound as well as object 
inventory sound names. llStopSound clears prim data and sends full update.
