Carts and Crafting!

Idea for improving obsolete minecarts.

Recipe changes: Crafting of rails could be changed to 4 iron & 2 sticks (in a layout like fences)

this would make Rails cheaper & easier to obtain, making them better for longer builds. powered rails could use the same recipe layout but with 4 copper, 1 stick & 1 redstone, similar again for a detector rail you just swap the redstone for any pressure plate.

Cart "Inventory" system. You will only be able to craft the default cart, however by opening the inventory while in a cart or by crouch clicking it (like horses), carts will have a new inventory & slot. You can place an item in the slot to change the cart type, (this makes it easier to build the carts you want, and means you can separate it from the block without having to break it, or you can swap a carts type whenever you want so you won't need to craft as many. (Can add the option after obtaining shulker boxes to use them in place of chests making it easier to load & unload carts with items!)

Add a Powered Cart! (made with a repeater in a cart's inventory slot), A cart that uses a redstone input to power itself for a set amount of time (4 to 10 seconds perhaps) this acts as an alternative to powered rail, it's active state can be refreshed by passing a torch, or over a detector rail or any rail on a redstone block. allowing you to power it as long as you need! (this doubles as a great way to make roller coasters!) (speed could also be determined by signal strength for further control.)
