Gravestone Fix (#18)

* Update Buildscript & deps

* Protect Graves against Hungry Nodes

Hungry Nodes no longer destroy graves.

Graves also take longer to dig up if you are not the owner.

* Apply Spotless

* Graves *feel* more secure

Graves are quicker to dig for owners.
As for grave robbers, it takes half as long as mining obsidian to access graves.

Shovels won't discriminate and will open all graves instantly as usual
