Adds various lights.
Dreambuilder is my attempt to give the player pretty much everything they could ever want to build with, and all the tools they should need to actually get the job done.
Adds various streetlight "spawners" (5m tall, supports multiple pole materials and light sources)
Early alpha. Improves the way light sources(torches etc) behave and allows to create huge lights, literal projectors with just a mouse click, light map will be computed for you.
