Major update to 0.5.0-beta!!

This update took the longest so far, but it also brings the most changes! It’s not just moving toward realism anymore, but also more toward fantasy!

--- Mainly: Sky ---

• Ember sparks at sunset and dynamic horizon color!
• Volumetric ray marching instead of 2D coverage, adaptive step count
• Multiple scattering, Worley erosion, domain warp, three types of cirrus clouds
• Night clouds with moonlight, temporal accumulation
• Haze between main clouds and cirrus clouds, carried by the wind.

Real lookup tables for the clouds! They look completely new now!

--- Light & Shadow ---

• SSAO, aerial perspective
• Static distant shadows beyond the shadow map
• Godrays through gaps in the clouds and terrain
• Aurora borealis shining in color onto the clouds!
• Grass shadows without blocky steps

--- Water ---

• SSR, caustics, underwater godrays, ice with Fresnel effects
• Shore foam with surf surges and undertow, based on actual water depth instead of a ray of sight
• Wind field + gusts to counter grid-like repetitions

--- Miscellaneous, New ---

• LICENSE.txt (ARR with permissions), CREDITS revised
• Menu with 158 options, bilingual, 866 entries per language (AI TRANSLATION!)
