Crude Glass

Back from the dead; now works with Polytone!

Changelog:

Added support for Polytone!
You can now use either Polytone or Translucent Glass! I may make a vanilla version in the future if any of these mods don't update.
Updated the pack.mcmeta to support 1.21.8.
The resource pack works perfectly fine on 1.21.9-1.21.10, but due to how the new pack formatting works, I can only define "support" for either 1.20.2-1.21.8, or 1.21.9-1.21.10. Once 1.22 comes out, I'll be switching to the new pack formatting.

Updated the credits file.
Updated the license file (the license itself didn't change).
Updated the pack.png to cleaner, better render of the glass block.
Updated the pack.mcmeta description to be consistant with my more recent projects.
Tweaked the colors for most of the Stained Glass textures.
Slightly reduced the opacity of normal Glass, and Tinted Glass
