[SizableShrimp]

Add jarJar.disable() Add jarJar.disableDefaultSources() Add configurations minecraftLibrary and minecraftEmbed minecraftLibrary = Non-MC libs that should be added to legacyClasspath (replaces https://gist.github.com/SizableShrimp/66b22f1b24c255e1491c8d98d3f11f83) minecraftEmbed = Deps that should be JIJed and put into implementation

People who want minecraftLibrary to also enable JIJ should use
