VanillaDynamicEmissives v1.1.1

Turns out, the way I was going to change the pack did not work whatsoever, so you're getting this patch instead. It changes the usage of light.glsl back to emissive_utils.glsl because it was only changed to make way for something that didn't work, and lessened compatibility. Also, you can now check the vertexDistance in the emissive check. Yay.
