Clean up character creation a bit

This fix takes out one of the areas we are "brute forcing" information to the client:

When a character is created we were adding them to the scene, this means the object was already in the scene and had its awareness built before the client began controlling it. This meant that the client had to be forced the creates for object in range on logging in.

Now the object is not added to the scene during the creation phase, instead letting the normal login process to select and load the character into the scene.
