The Aether: Redux

finally finished this one
Another update! This one brings a number of quality-of-life features, along with some stuff from the WIP 2.1 update that will be on (most likely) 1.21.

CHANGELOG:

+ New metal, Refined Sentrite; this can be used to craft lanterns and chains
+ Upgraded the Gilded Groves based on the in-progress 2.1 design
+ New tree shape for regular Skyroot trees (slightly rounder) plus a secondary Golden Oak shape
* Renamed the Valkyrie Ring to the Ring of Construction
* Improved colors and systems for Redux's sky colors, grass colors, and water colors
* Made Swet drops scale based on their size
* Tweaked a few textures
- Deprecated and removed survival access to Veridium Lanterns and Chains
- Deprecated and removed survival access to Gilded Vines (Golden Vines, however, continue to generate naturally and are not deprecated)
> Fixed bugs with Golden Vines
* Golden Vines now require shears to drop
* A variety of internal improvements and rewrites
> Fixed a few crashes
> Miscellaneous fixes
