Relumination

Just a few small tweaks to night fog to make it less thick near the player.

Added atmosphere and fog which changes based on time of day (see if you can make it to space! yes, you can exit the atmosphere if you get high enough but this is way above the build limit as to not interfere with the environment of your builds).

Just a quick fix to support certain newer versions of iris. New versions of iris prevent shaders from naming values 'sample' (due to gpu compatibility)

Implemented wavy blocks (waves snap to pixels to provide a blocky feel) and basic bloom.

• The tops of water and lava now wave up and down
• Leaves and other other foliage including vines now wave
• Basic single pass box blur bloom (coming updates should improve this both visually and in performance)

This update was originally going to include changes to the atmosphere and clouds, but to avoid delaying any further it will be split into the next update.

New tonemap and a couple of lighting tweaks

• Switched from Reinhard to Uchimura tonemap (Provides higher contrast in lighting)
• Fixed issue with calculation of ambient light (Previously had unexpected dependence on directional lights)
• Tweaked lighting to better fit the new tonemap
