Register.lua: Throw error if node 'light_source' > core.LIGHT_MAX
Add 'core.LIGHT_MAX = 14' to builtin/game/constants.lua with the intention to replace misplaced 'default.LIGHT_MAX = 14' in Minetest Game. Add comment in light.h requiring the constant be changed in both places. Add lighting bug warning to note in lua_api.txt. There are hundreds of mod uses of 15 which causes a lighting bug.
