Old Lighting & Water

Not supported in this version:
Underwater particles are invisible (pre-Beta 1.8). Because if the particle was made invisible, it would also affect explosions.
Accurate color for cold/warm rain/thunder sky (pre-Beta 1.8). When it rains in cold or warm biomes, the sky is shown as temperate because Biome Id is not recognised for some biomes. If you want the normal sky, just delete the files you don't need in the .zip file.
