When sacrificing buildings (such as cursors to upgrade the Stock minigame office) display the replacement cost in cookies

[TakGalaman]

Sacrificing buildings to get some benefit like changing Krumblor auras or upgrading the Stock minigame's office can be difficult to asses in terms of cost/reward.

One concrete thing we can show the user is how much it will cost to buy-back the buildings that are to be sacrificed. In the screenshot I could sacrifice 350 cursors. How many minutes of CPS is that for me? It would be easier to decide if I knew it was like 5 seconds vs 5 days.
