Ender Pearl: Add an Elite version of the reusable Ender Pearl.

The Elite version mounts the player on top of itself when thrown.
Release 0.3.5
Ender Pearl: Fix Elite Pearl not dealing damage. Fix tp'ing inside blocks.

The fix for teleporting inside blocks is kind of a workaround.
For some reason the MovingObjectPosition hitVec goes inside blocks
if the projectile is moving too fast (or something).
So for now, I'm just moving the entity up until it is in non-colliding
blocks.
Release 0.3.5.1 to fix some of the Elite Ender Pearl stuff.
