Entity names don't match any other MC version

In MCPE Iron Golem is caled: irongolem
In 1.10.2 PC version it's called: VillagerGolem
In 1.11 PC snapshots it's called: villager_golem

This is true for other entities as well, commands also don't accept Cow when summoning a cow. Only the lower-case version will get accepted.

This may not be a bug, but it is an inconsistency.
