- fixed: Trace should set CrossedWater only if a water surface actually is crossed, i.e. the start of the trace and the end of the trace are on different sides of the surface. 

This was incorrectly spawning splashes when shooting inside a deep water sector, but in most cases the splash just was not visible. It could become visible if its position got clipped by a nearby one-sided wall.
