quarry.lua
Quarry machine to dig stones and other ground blocks.
The Quarry digs a hole 5x5 blocks large and up to 25 blocks deep.
It starts at the given level (0 is same level as the quarry block,
1 is one level higher and so on)) and goes down to the given depth number.
It digs one block every 4 seconds.
It requires one item Bio Fuel per 16 blocks.
