Sorry unknown material for advancements

If your the leader of a village (crystal ball) you also choose what kind of village you can make
Misc: With each advancement more availability of tools weapons materials blocks and structures
Plus more ore and ability to be polygamous
Edit to to have a family: you will be put in a random sized and type village and will work there if you can kill the leader you will lead that village but the archers and guards will attack you also you will be able to act as a npc
Adds shops and currency
Also could you make villages more common and also they can be made in any biome.(Like one in each biome)

This isn't really the place for suggestions, but I'm going to mark this as a feature to pick through later.
