Title: closed #4763: fix some problems in cocosdension in wp8

1.fix stopalleffect lead to stop background music
2.fix play effect may lead to memory leak
@stammen in fix 2, I think StopAllSoundEffects should call UnloadSoundEffect to free memory or may lead to memory leak when you dont UnloadSoundEffect by yourself. Please review.
