Add experimental "OpenSim object memory churn" statistics to output of region console "show stats" command 

This aims to capture the amount of memory that OpenSim turns over whilst operating a region.
This memory is not lost - apart from leaks it is reclaimed by the garbage collector.
However, the more memory that gets turned over the more work the GC has to do to reclaim it.
