Position: add getLevelNonNull()

Browse Source 
this allows assuming that a position has a valid world in places where it's never expected to not be valid. Since this is the vast majority of usages, it eliminates a lot of possible null-pointer warnings given by static analysers.
TODO: Consider whether we can make Position->getLevel/World use this behaviour out of the box in the next major version.
