Adding bones' drop feature Before, when you died, you got to punch you bones to get back your stuff, the bones block was not dropped. However, a lot of people wants to use them for decorations/building, and have to install a dedicated mod since 0.4.10-release. With this commit, a bones block containing an inventory is dropped/added to inventory (if enough room) when the bones block is removed. Then, when a player places a bones block by himself, he will dig it like any other basic node (eg. default:tree), not just punch it.
