Subject: Adds an event and a method so that handling of the CachedTexture
 packet can be pulled out of LLClientView and moved to AvatarFactory. The
 first pass at reusing textures (turned off by default) is included. When
 reusing textures, if the baked textures from a previous login are still in
 the asset service (which generally means that they are in the simulator's
 cache) then the avatar will not need to rebake. This is both a performance
 improvement (specifically that an avatars baked textures do not need to be
 sent to other users who have the old textures cached) and a resource
 improvement (don't have to deal with duplicate bakes in the asset service
 cache).
