Add a "resource" world

[MilesBHuff]

#183 should allow us to add a "resource" world like Tyler had suggested back in the days of SettlersMC. This world would be one for players to visit and strip bare of its resources without concern for aesthetics or propriety. I would additionally make such "resource" worlds more-or-less anarchy, for an added layer of excitement. They would reset on a regular basis.

These resource worlds will also allow players to experience the latest terrain generations without us automatically needing to commit to maintaining another world long-term (though we will remain open to doing so).
