Pathinator

Add new command path:dig which will excavate for you without adding any blocks. up|down will dig a stair step passage (1 forward, and 1 up|down), ahead will dig straight ahead, and vup|vdown will dig straight up or down from 1 block in front of you.

For example, path:dig down 20 will dig a stair step passage 20 blocks long going down 1 block at a time.

Additionally, this release supports SILK_TOUCH and FORTUNE when collecting material, and UNBREAKING when calculating tool damage. (NOTE the calculations are not exactly the same as in regular Minecraft, but they are pretty close).
