The Aether: Redux

UPDATE 1.0 PRE-RELEASE 2 This is a relatively small pre-release, fixing some bugs and improving some internal systems. It also adds a new mushroom!

CHANGELOG:

• Added a new mushroom, the Aershroom, to the Highfields, replacing the Cloudcap Mushlings that previously spawned there (although they still spawn in their own biome, the Cloudcap Jungle)
• Conversion of the different Aether Grass types is now handled by a more modular system
• Biome parameters (Temperature, Humidity, etc) can now be configured
• Default Aether biomes can now spawn between redux ones
• Fixed the 'Take THAT, Physics!' Advancement being granted while not wearing a Sentry Ring
• Fixed Mimic open animations not working
• Fixed Cockatrices not dropping their ribs without the Aether: Genesis installed
• Made Enchanted Vertisol mineable with shovels
• Switched from Parchement mappings to Sugarcane mappings (has absolutely no impact on the built code)
