Subject: renamed SoundMixer::hasActiveChannel->hasActiveSFXChannel, and fixed
 the regression in it caused by removing _beginSlots (I hope); added
 isActiveChannel method used by scumm/sound.cpp (this allowed me to move the
 Channel class from mixer.h into mixer.cpp); replaced Channel::soundFinished
 method by isActive
