Winter Wonder Land

This mod does one thing and one thing only: makes snow accumulate in Minecraft.
 
If it is thundersnowing,  the rate of snow accumulation doubles.

Snow accumulates up to a single block in depth by default.  This can be configured

Config Options:

• Accumulation Rate: How quickly snow accumulates
• Smoothing: How many sides need to be at the same level before more snow is allowed to accumulate
• Snow Drift Size: Number of blocks to increase the snow level at around a snow accumulation event 
• Max Snow Layers: Each snow block is broken into 8 layers.  Sizes above 8 are treated as multiple blocks
• Snow Melt Rate: How quickly snow melts
• Snow Min Layers: Layer to melt down to.  This prevents wintery biomes from turning brown and bare with extended periods without snow.
