Distinguish between mobs using the same entity class

[Chimaine]

MobTalker2 must be able to distinguish between mobs using the same entity class, like Skeletons and Wither Skeletons, where the only difference is a flag set in the entity's data.

Other cases are:

• Creepers and Charged Creepers
• Different Villiger types
• Slime sizes
• Adult and child mobs

[Chimaine]

Introduced new way to retrieve the name for a given entity. Closes #7 Makes it possible to differentiate between mobs that use the same class, like Wither Skeletons.
