Refactor appearance and avatar data sending code. Paritioning the routines into "one-to-many" and "many-to-one" makes it possible to call the right function on presence creation (both child and root) and when a child agent is promoted to root. This brings the total number of appearance sends down to one or two on login.

Cleaned up the avatar update calls in the groups code. Cleaned up
some commented and debugging code, and a few formating fixes.
