Part 1 of a commit. This revision will not compile, part 2 will be added in a couple of minutes that should fix that.

Some work towards persisting Avatar Appearance (what is being worn).
Added OnAvatarNowWearing event to IClientAPI that is triggered by AgentIsNowWearing packets.
stub code to subscribe to this event in AvatarFactoryModule. 
Todo: code needs to be added to AvatarFactoryModule to save the uuids to a database and then read them back when that modules TryGetIntialAvatarAppearance() method is called.
Done some changes to Scene to make it easier to subclass it: including changed some private fields to protected and made some methods virtual.
