Horse overhauls

Maybe to not rule out horses as a late game travel solution and to make roads useful to build (as opposed to being purely decorative), you could add speed boosts when riding horses, as well as just walking on, certain blocks. Here are some examples, 5% speed boost when on path blocks, a 10% boost to walking speed if walking on wood planks, 15% boost when riding on cobblestone blocks, and a additional boost for horses if wearing a special equippable item called a horseshoe that would stack with other boosts
