NEVERHOOD: Try to fix the Smacker issues inside of SmackerPlayer only (instead the numerous classes using it)

SmackerPlayer now creates a surface in the constructor and deletes it in the destructor. There will be only this surface during the lifetime of the player, so there shouldn't be any issues any more when the player is reused for different Smacker files. This is imo nicer than to remove/add the surface.
I kept the several openSmacker since it wraps some code which is nice.
