* Initial work towards Fabric compat. This does not compile yet * Further updates - should compile but Gradle is being weird. * Remove useless buildscript extras * Added mixins to buildscript classpath to fix Loom crash * Make it compile * Got it building and added interaction * Fixed review comments * Use ServerPlayerEntity for FakePlayer * Use method references for nicer names * Fixed remaining comments and added networking for CUI * Output as dist.jar * Added mixins for left click air * Use regex for cleanliness
