1.19.4

I wouldn't recommend merging this as-is, since the ItemGroup entry registration is likely not done very efficiently / properly (and I unfortunately don't know enough Java to do it the "right" way at the moment). But it works!!

• Update Gradle, Loom, dependencies, etc. (and added Quiltflower)
• Declare dependency version numbers in gradle.properties for ease of management
• Add shedaniel's maven to build.gradle (it wouldn't load the project without it...?)
• Remove Spirit compat, as the mod has not yet been updated for 1.19.4

Closing, as it seems support for 1.19.4 was skipped in favor of 1.20. Probably for the best!

Yea sorry, I've mostly been playing on 1.19.2 so I've been avoiding touching most of .3 and .4 for most of my mods, mostly doing all the 1.20 ports to have them ready for blanketcon.
