Light tiles are NO LONGER FUCKED!!! Fixes #4436 (closed) and Fixes #4247 (closed) -Making a light tile now uses 2 lengths of cable instead of 5 (you get 15 tiles instead of 6) -While making light tiles, new tiles will automatically merge together into one stack -There is no longer a delay on finishing the tiles with metal -Light tiles no longer have a chance to spawn broken or flashing, this is because of the way that feature behaved with stacks. I'll work on it in the future
