Version 1.0_2, attempt 2

This time, the bugs fixed weren't necessarily game breaking, but are still worth fixing:

• I missed clouds when creating the new light renderer. Unfortunately, they have to look a bit weird now, due to transparency stuff being dumb. Actually, I kinda like this new look.
• Also, the level editor was slightly brighter for some reason, and possibly had some flickering when moving around. These issues are fine now.
