#29 Avatars are not implemented.

[John Chapman]

We need:

1) Netapi Avatar implementation.
2) An Avatar "class" to ease rendering and management of avatars, particularly with respect to needing to download avatars DURING game play, not all at the start (So need to use a default avatar texture and then update it with the latest version when it becomes available.)
3) Lua bindings to this in a "safe" way, for the lua games, and lua bindings to allow the user ot change their avatar from the theme.
4) Lua bindings to allow changes of "emotion", do emotions need to be sent to the server?
