Add a basic sky

[mike]

Problem

When you look up, there's nothing but blackness. There should be a sky with clouds and so forth.

Solution

Added a sky element to realms and set up basic handling of dependent classes when sending class generators in playerview. So the sky's view is sent and a client side view picks it up. A similar technique could be used in areas for items that are very big and very far away so you could get a distant view of a tower without it being in the area or having the view be extended that far.
