Adding ability to alert on low world mine

Currently, we have no alert when a world mine is about to run out.
Suggestion: Add a little toggleable bell icon in the reserve status section.
Clicking the alert should bring you to the world map, centred on the world mine, selected.

Would also be nice to get alerts for if the world mine storage is full. Useful for early-mid game so you can keep track of when to send the ship (if you're doing it manually) or if you're using the world mines as emergency reserves so you can know when you can set production back to zero.
