Show enderbar in different ways to the players

In the last update for 1.7.9/10, the dragon gets teleported to the direction the players looks to.
Could you make it so, that the dragon behaves for 1.7.10 clients like before, and only gets teleported to the players point of view, when he's on 1.8+?
Anyways, thanks for this great plugin!

Requires a slight refactor to implement. To see if Mojang fixes the client side issue or not before starting.
