Faster block break Lighting updates

[valoeghese]

Spread light one block further into opaque with forced termination to make it easier to recalculate. Either that or make single block breaks update lighting faster by having an immediate step for updating 1-2 block (PREFERRED). Lighting seems to take up quite a bit of time on the thread

can I reduce time relighting one chunk by more intelligently handling relighting the chunk? Perhaps abuse the fact that only the segment directly against the chunk from neighbours has any chance of propagating into the chunk to reduce calculations

also when am i making fov a setting
