GreyMario 40310688ed yCoordhelper: added top-down search (may be redundant)
This is used for the code that determines where to come out of Limbo in. It tries to search from the top down to find a solid block to stand on. Isn't complete, though. This code does need some considerations put in, though... I'm concerned about Natura's clouds, for instance.
