-Also fixes a bug where bulb type didn't matter when inserting a new bulb into a light fixture.
-And a bug where bulb state changing didn't change the light itself.
P.S. Also note I didn't add any colored lightbulb prototypes, as I don't think they're necessary right now. To see the changes, please use VV! In the future, it might be possible to change the lightbulb's color with a multitool or something in-game.
