Subject: * 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
