Winter mode

Winter mode is available from options. It makes all the grass cover with snow. Some buildings are also covered with snow. Instead of rain, snow falls.

Winter mode was first introduced in version alpha 1.0.67, but it was permanent and you couldn't disable it. It was removed in beta 1.1.12. Then it was re-added in beta 1.2.10 with a possiblity to enable and disable it.
