Bug fix for grabbing/equipping large objects, they no longer will drop immediately
if your grab point is too far away from the grabbed entity position.
You can do this by parenting an entity to an avatar's -2 joint index.
This will mean that the entity will follow the avatar as it moves in the world, but
will not follow the avatar's position as it moves in sensor space. Essentially, this
gives you the ability to place objects in the user's physical room.
WebTablets now are located in this feature and no longer jitter.
