winter effects

- once snow melts on a tile, it has a 50% chance to get rid of logs, animal skeletons, abandoned man-made objects (example anvil), and speeds up decay (on non-claimed tiles)
- snow should melt 2-3 tiles around fire objects for as long as fire is on

This is neat. The fire thing has been suggested and I think I jorb said maybe. I wonder if the server would benefit a ton from a clean up like this. Kinda like it but kind of dont want to lose my packet ness.

Just to clarify: *all* the mentioned could happen only on non-claimed tiles:
