Stop hull rays from passing between occluding blocks

Browse Source 
A ray only moves diagonally if it could also reach the block by moving along
the single axes of the direction one after another without passing an
occluding block, so it no longer squeezes between blocks touching at an edge
or corner. When a block stops occluding, the diagonal rays it blocked are
continued, so incremental updates match a full initialisation.

Double slabs now occlude as well, as slab materials do not; block updates
pass the block data instead of the material for that.

To keep the initialisation fast, a ray only checks a diagonal step after the
cheaper checks, and the branch directions are computed once per hull.
