Made the Enemy sprites fall to simple movement mode when failing at finding a path.

But also move random when not chasing the player or following way points.

This permitted to lower the pathfinding cost and get no fps decrease at all
on my own, while keeping the benefits of pathfinding where relevant.
Added support for basic collision checking at the scripting level.
Added a rolling stone for future use. ;)
Added stone triggers needed along with the rolling stones.
Added the next two maps (still WIP) and polished the first two.
Added missing landing sounds when jumping.
