This seems to have caught some params as well which is not undesirable IMO.
It also caught some strings containing this which is undesirable so I
excluded them manually. (engines/sci/engine/kernel_tables.h)
It actually was stopMusic() before and so stopped only the music and not all sounds.
The former implementation is for the o_stopMusic opcode which is not supported directly by ScummVM (it always stops all sounds). It is kept as stopMusic_intern() but is not used anymore.
