[1.21.10] Implement Greenhouse Config, and other stuff

[ChrysanthCow]

Resolves #65

I will mark this as ready when possible.

Features

Specter Config is gone!

• Implemented Greenhouse Config.
  • Also includes a data fixer.
  • Greenhouse Config is not on my maven as of yet, as there are some things that need to be ironed out within its implementation.

Mapping Migration!

• Swapped mappings to Mojmap for an easier time with deobfuscated versions.

General Porting!

• I've pretty much ported everything besides the config screen. I think that's on y'all to implement.

Quality Passes!

• Tweaked Screenshot Toast size to the below, I'd like to discuss the ideal state for this to be in. It may look bad on higher GUI scales. The main thing is that I wanted to shrink the margins of the edges of the toast.
• Screenshots now stay inside the box rather than overflowing onto the lines.
• Fixed the margins of scrolling to the bottom to match the top.
