Minecarts still use ids to display blocks

NEVERMIND

using the command:

/summon Minecart 10 50 10

{CustomDisplayTile:1,DisplayTile:80,DisplayData:0,DisplayOffset:0}

works, however the command:

/summon Minecart 10 50 10 {CustomDisplayTile:1,DisplayTile:

{"snow"},DisplayData:0,DisplayOffset:0}

does not. This because {"snow"}

is not recognised. Only the ID for snow is.
