Forget-Me-Not Shaders

Hi everyone!

v0.6.0 was originally planned to be a small update, but it's turned out to be quite phenomenal. Here are some of the changes:

• Added seasons! Everyone's world is going to be a little more magical with the first-ever implementation of seasons in a Minecraft shaderpack
• Added material shaders for most vanilla materials. Are you a Lumi Lights, Lomo, or Canvas Standard user? You can still enjoy your favorite pipelines as usual, but if you activate Forget-me-not's resource pack, you'll get some pretty emissive lights
• Added water refraction
• Adjusted bloom
• Adjusted fog scattering / bloomy fog

API changes (FMN PBR version 3):

• When fmn_isFoliage is set to 1 and the material uses vertex tint, seasons will dynamically change the color of the material
• When fmn_isLeafBlock is set to 1 and the material uses vertex tint, trees will get some additional color changes based on noise

Forget-me-not is in the need of a major rework for both performance and ease of use, so that's probably what I will work on next. Unless I get another idea similar to seasons. Enjoy!
