Unclear documentation

[1b8]

Some of the documentation is unclear:

Is id the unique entity id, the numerical entity type id, or the entity name?

What's the difference between mobType, entityType and objectType?

What is player?

It's also unclear that position and velocity are Vec3s.

• id is the unique entity id (not the type)
• entityType is the numerical type, mobType and objectType are the type in letters, I agree these names are bad, maybe they should be type and name instead
• players are entities, entity.player is the player of the entity if entity is a player. It's kind of optional, I don't think any code use this anymore, it could probably be removed
• yeah they are indeed

I'll clarify the doc / make the changes needing to clarify stuff.
