Title: fixed some volume and audio issues

1) This fixes volume issues on Linux and makes the volume which is used to play sound effects relative to the master volume (as on windows).
2) Already had that fixed before but I guess it was lost in another commit: UnloadContent() isn't called by the Game class.
