Ebin Resurrected v1.2

I swear I'll make these less frequent in the future.

Volumetric Fog

I managed to get the volumetric fog code left behind from before Bruce added the precomputed atmosphere working again! Note that on higher render distances you may need to decrease the fog curve for it to be noticeable. I am hoping to get this working with water as well at some point in the future.

Glowing Ores

Ores now optionally glow in the dark, so you can see them better.

Shiny Rails + Fixed Redstone Emission

Rails are now nice and shiny. I also cleaned up the emission for redstone components. Observers now have emission when activated, and it's easier to tell the power level of redstone dust.

Stuff

• Using the shaderLABS modded block ID list, I've added waving leaves to mods like Biomes O' Plenty. Since this list is not exhaustive and somewhat outdated, some blocks will definitely have been missed.
• The shader will now load on hardware which doesn't have custom image support. I've no idea if there is such a thing as a GPU that supports openGL 4.3 but not custom images, but if there is, now you have compat!
