Fix clone loading race condition.

This happens on DirtSand shards when two avatars are loading the same age
at once. LoadCloneMsgs are dispatched to the clients before they have
loaded the original keys. The server has no way of knowing that however,
so this is the correct place to fix the problem.

Fix crazy camera stack issues

Turns out, it was an artifact of us suspending the simulation during links
and partly because of Cyan's late adding of the avatar controller to the
sim. Now, we add the avatar as soon as the age data is loaded. This causes
the camera stack to be populated with whatever garbage PhysX decides on,
then xJourneyClothsGen2 is free to set the real stack after we get all the
SDL from the server.

Verified to fix Teledahn oddness and not display a regression in Kemo.
