Food preservation using ice

[citrushook]

I'm aware that there's probably a mod that does this, but I'm hoping it will be made native to the game. Having any ice blocks in your cellar could significantly decrease the spoil rate of food, with a bigger penalty given for direct contact with your chosen storage vessel than simply having it in the room. All ice blocks, though, would now melt and become water given time, for balancing purposes. As a trade-off, maybe you could gain the ability to harvest lake ice in a manner similar to harvesting whole stone blocks. Ergo, carving out the blocks around it to harvest the whole piece. Maybe placing an ice block or two in a cellar would also provide sort of a bonus?
