Heat Stones for temporary warmth

[MondoDopeness]

I think it would be cool to be able to "cook" stones on a campfire or stove cooking slot... then after they are heated, you could carry them for a temporary warming effect, like the tea provides. Since they are a heavy item, it makes them slightly worth carrying, vs. just using them for stoning rabbits and then dropping immediately after. This could also prevent frostbite on the hands in harder difficulty settings.

I like preparation things like this. Coffee to fuel climbing activities(which makes no sense to me), drinking tea before going out, repairing your gear before a longer expedition, bringing a lamp for a cave. I think it would be cool if we could sleep with cooked stone as well.
