Collision Damage Port

This is a port of fonnymunkey's Collision Damage. All credit goes to its original author.

This mod adds acceleration-based collision damage.

This mod uses the modern FMLJavaModLoadingContext constructor, mod event bus, and Dist.CLIENT. Networking is replaced with a SimpleChannel using protocol versioning, FriendlyByteBuf, and a Supplier<NetworkEvent.Context> handler. Config's are replaced with ForgeConfigSpec. Mappings updated. 

The core damage formula is unchanged from the original. If you want this acceleration-based damage mechanic with more features, try Full Stop! by justcama: https://www.curseforge.com/minecraft/mc-mods/full-stop/files/5869563

maxDamage: Cap maximum damage per hit.

ignoreWhenRiding: Skip damage while on boats, horses, etc.

ignoreInWater: Skip damage when underwater.

Include Y Axis: Include Y Axis collision damage from upward impacts.

Vehicle collision damage: When a rider crashes, the vehicle will take the same damage.
