* Add asset/texture cache statistics to region server console

* You can type 'stats' at the REGION# prompt to get this information in grid or standalone mode
* Don't take these numbers as gospel yet, since for some reason textures displayed from inventory which require downloading from the server are being recorded as assets 
rather than textures
* But I don't have any reason to believe they aren't broadly accurate.
* I've put these in so I can tell whether the high memory usage on regions is down to the asset/texture cache
* This will require a prebuild
* DEV: Only adds needed to be implemented since, as far as I can tell, assets cached are currently never released.  For my part, seeing large cache memory numbers will 
provoke me to think about doing something about this.
* DEV: Now switched to using a singleton to get the stats reporters rather than threading the object through various layers
* DEV: Will refactor the other server stats reporters to do this in one of the next commits
