Digging Wells

[dotSp0T]

Add functionality for digging wells

• dependent on soil/rocklayer(s)
• each kind of rock could get a function that defines how much water a block stores (or area or whatnot)
• could create underground acquifiers that 'wetten' the surrounding areas (up to a few dozen blocks?)

possible ways of creating (choose one, obv..):

• special well-block that is placed atop the well?
• could just say that digging 1by1 straight-down creates a hole that slowly fills with water (could expand to having to drain mines?)
• could say that a well needs to be lined with certain block(s) (e.g. brick?)
