* Check in (disabled) results of not persisting avatar textures but rather sending ImageNotFound to clients if avatar textures are missing

* Whilst this does automatically get the client to rebake, on crossing a region border the 'local' assets are left behind
* There may be a cunning solution (such as squirting the assets on region crossing, or having them fetched from the original region) but 
instead I'm going to opt for the easy solution of keeping them in the asset database, for now
