Show Mob Spawning blocks

Make a Command like /ShowMobSpawns that would allow you to see what kinds of mobs can spawn on a block currently (by having a small texture that would be like a Red X for hostile mobs and a Green Plus for passive mobs and a plus with an X for both) that would allow players working on lighting up their builds to be able to easily see what blocks need more light to make sure hostile mobs don't spawn where they don't want them to spawn. It would also make an easier way for newer players to figure out what blocks hostile mobs can spawn on so they can place torches accordingly.
