Subtle Effects

Still no Forge port :/ but I think I am making progress so maybe next update?

• Amethyst will now randomly play sparkle sounds
• Improved list configs validation
• New "Cull Particles With No Alpha" config (defaults to true). If particles from other mods aren't rendering (Particular leaves specifically) try disabling this. Fixes #10
• Warnings in config descriptions are now colored red for better visibility
• Rain is now colored to match biome water color
• New built in resource pack which will cause all vanilla water particles to match biome water color
