Media - ugly fix

- Fix stop button not working
- Fix previous track not stopping when new one played.
- Note: I had to use Sound_GameSystem_RestartSoundSystem(), which triggers a client freeze, but it's the only way i could find, since there is no StopSound() api.
I also do not undertsand what is a musicHandle local, and why it's always false?
