Horses Still Use Their Entity Code Name

When riding on a tamed horse, mule or donkey, they still use their entity codes.

Horse = entity.horse.name
Mule = entity.mule.name
Donkey = entity.donkey.name
Zombie Horse = entity.zombiehorse.name
Skeleton Horse = entity.skeletonhorse.name

Zombie Horse and Skeleton Horse can be ridden using the command below:

/entitydata @e[type=EntityHorse] {Temper:0,SaddleItem:{id:"minecraft:saddle",Count:1b,Damage:0s},Tame:1b}

It also works if you use the command below

/say @e[type=EntityHorse]

All the results that return from the executed command use the code names instead of the real in-game names.
