Fixed multiple issues with lighting

[moorehousew]

Chunk boundaries and special blocks are still lit incorrectly, but regular blocks work fine now.

Woot!

This is cool as shit, nice work!

Thanks. On another note, I've added a WorldLighting instance to ReadOnlyWorld, it calls the same lighting code the server does during various world-related events (chunk load, block change, etc.), yet the light level doesn't seem to change anywhere. Thoughts?

I can't look into it too much while I'm at work, but I'll take a look later today and see what I can find out.

Okay, here's the commit for when you're free: https://github.com/mrpimpunicorn/TrueCraft/commit/bd51718743b4d163b4957a7a74d1c8d9ee316b69

Okay, the issue is that the chunks have TerrainPopulated = false, which causes lighting operations to have no effect. I implemented relighting myself - but it ends up in some sort of feedback loop that freezes the game by queueing lighting operations exponentially. My work is in the lighting-fixes branch, will take another look later.
