Throw Ropes

A rope which you throw and then climb. The item is throwable like snowballs and eggs. After thowing the rope, an "anchor block" (which acts like an entity) would spawn at the location and a rope would make its way down to the thrower. There should be a limit to the distance a rope would go. Also, the rope should not come down instantly. Maybe it could travel like 10 blocks a second. After the rope comes down, any players can climb it. The rope disappears after one in game day or once the anchor block is broken. The crafting recipe could be a lead with iron and slime. When the rope is broken, you get the lead back.
