Some of the "wall broken" checks were inverse, resulting in the waterfall
sound being incorrectly heard when the wall was broken. Also,
simplified some of the "wall broken" checks
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.
These are shown on each scene change, but should no longer be needed
to be enabled by default, since we can now use the debugger to check
and change the current scene
