Converted the internal system to capabilities
- Removed profile system to instead wrap around present minecart classes, increasing compatibility w/ other mods.
- Added cart recipes.
- Overrode the vanilla Minecart with Furnace with a custom entity that performs just like as if it had the Furnace Profile loaded from prior versions (supports all fuel types & will consistently move while burning).
- Fixed the vanilla furnace cart bug where after world reload the furnace in the cart isn't lit.
- Blocks can still be removed from carts by shift+right-click, and placed in them by just right-click.
TODO:
- Fix smoke particles not being generated from the furnace cart after world reload.
NOTE: Prior MetalTransport worlds will have just about everything old deleted, so be prepared!
