Add optional support for the https://github.com/Chisel-Team/ConnectedTexturesMod so we can have emissive maps, similar to what was previously done with Dynamic Lights (see #992). Should be done primarily through MCMeta files, though some JSON and art modifications may be necessary. Blocks to support:

• Charge Feeders
• Diamond and Emerald Dark Ores
• Flux Transformers and manipulators
• Force Tracks and Emitters
• Track Kits (enabled)
• Boilers
• Firestone ore and ritual

Other blocks may also be considered

Those two selected ones are not done yet.

Should be something like this: https://github.com/Chisel-Team/ConnectedTexturesPack/blob/master/assets/minecraft/textures/blocks/redstone_block_glow_0.png.mcmeta

Btw this should go to another repo possibly (like railcraft 3d)

See #1198 and #460
