Light calculation: New bulk node lighting code

Browse source 
This commit introduces a new bulk node lighting algorithm to minimize
lighting bugs during l-system tree generation, schematic placement and
non-mapgen-object lua voxelmanip light calculation.

If the block above the changed area is not loaded, it gets loaded to avoid
lighting bugs.
Light is updated as soon as write_to_map is called on a voxel manipulator,
therefore update_map does nothing.
