Good start

Hello, Era! Mining and Digging have been updated.

Changes to mining:
-4 new* minerals have been added (Quartz, Gypsum, Silver, and Copper)
-Drop rates have been adjusted to accomodate the new minerals
-Prices of minerals have been raised across the board**

Changes to digging:
-Shells prices have been doubled***
(Prices maybe be increased again if they're too low)

Changes to businesses:
-All businesses which require lead or iron to stock have been compensated for the increased price of minerals. They now stock 3 times as much as they previously did per mineral.

Other jobs are soon to be updated as well.

Happy mining/digging!


*Oldbies will probably recognize most of these minerals from a while ago.
