Create: Crude & Current

### Screens
- Machine screens in the style of Create's Stock Keeper: coke oven, blast furnace, hot blast stove and deep drill, and new ones for the distillation tower (its stages and heat) and the engine controller
- Furnaces get a button to dump their tank
- Engine controller: right-click opens its screen. The throttle follows redstone or is set by hand; the screen also shows the gear and the engine's speed, stress capacity and fuel use

### Roads
- Asphalt, asphalt slab and stairs: bitumen, gravel (or crushed slag) and sand in a heated mixer. Walking on it is about a quarter faster
- Road markings: any dye paints a line on asphalt or its slab; the same dye again changes the pattern (solid, dashed, edge), the wrench turns it. Deployers paint too

### Slag
- Crushing wheels turn slag into crushed slag, with a chance of an iron nugget
- Slag is a poor fertiliser: it works like bone meal one time in two

### Recipes
- Block variants (hatches, fuel intakes, tower windows and ports, furnace bricks) are made by item application, as Create's casings; drill bits, surface scanners and large generator stators by sequenced assembly; refractory bricks by compacting, well pipes by pressing, copper cable by mixing

### Fixes
- Belts over steel, cast iron or lead shafts keep them when lengthened, shortened or split, and give the right shafts back; splitting a belt takes these shafts from the inventory
- The engine goggles no longer say "out of fuel" while the engine runs
- Tested on a dedicated server
