Returns false if sunlight at bottom block is invalid.
Returns true if sunlight at bottom block is valid.
Returns true if bottom block doesn't exist.
If there is a block above, continues from it.
If there is no block above, assumes there is sunlight, unless

At the moment, all sunlighted nodes are added to light_sources.

All sunlighted nodes are added to light_sources.
Turns sunglighted mud into grass.
If grow_grass==true, turns sunglighted mud into grass.
if remove_light==true, sets non-sunlighted nodes black.
