Frosted Block variants

Cobblestone, Glass and its color variants, sand, Deepslate, and all decorative stone blocks would now have Frosted variants.  They look similar to textures in the Festive mash-up(minus the color change.  So, just the snow/ice part) and some blocks have special effects.  For example, Frosted glass can't be seen through, Frosted sand ignores gravity, and frosted stones take longer to mine.  They are created when you put a top snow block on top of a designated block, then wait for 2 minutes.  But, when a full snow block is put on top, the three blocks below the snow are frosted(afied).  A powdered snow block changes the 5 below it.  An ice block melting on top of the block can also makes it frosty.  They don't have much of a use, but they would look cool, and be a tad slippery.  (secret slipperiness is great for traps)
